Sun Yang
Sun Yang is a Chinese Olympic and world-record-holding competitive swimmer. In 2012, Sun became the first Chinese man to win an Olympic gold medal in swimming. Sun is the first male swimmer in history to earn Olympic and World Championship gold medals at every freestyle distance between 200 and 1500 metres. A three-time Olympic gold medallist and eleven-time world champion, he is the most decorated Chinese swimmer in history. In 2017, NBC Sports described him as "arguably the greatest freestyle swimmer of all time".
Sun competed for China at the 2008 Summer Olympics. In 2010, he won the 1500 metre freestyle at the Asian Games, setting a new Asian record. At the 2011 World Championships, he beat the 1500 metre freestyle world record, which was previously held by Grant Hackett in 2001 and the longest-held world record in swimming at the time. Sun won gold medals in the 400 and 1500 metre freestyle at the 2012 Summer Olympics. At the 2013 World Championships, he became the second swimmer, after Hackett, to win gold medals in all three long distance freestyle events in a single World Championship.
At the 2016 Summer Olympics, Sun won a gold medal in the 200 metre freestyle and a silver medal in the 400 metre freestyle. By winning the 200 metre freestyle, he became the first swimmer in history to win Olympic gold medals in the 200, 400, and 1500 metre freestyle events. At the 2017 World Championships, he won his first world title in the 200 metre freestyle, setting a new Asian record. He won his third consecutive title in the 400 metre freestyle, the second swimmer to do so after Ian Thorpe in 2003. In 2018, Sun won gold medals in every freestyle event at the Asian Games, as well as silver medals in two relay events. In 2019, he successfully defended his titles in the 200 and 400 metre freestyle events at the World Championships. As of 2020, Sun Yang's 1500 metre world record remains the only Men's Individual Freestyle long course world record achieved without the use of the high-tech swimwear that controversially dominated swimming victories and records in the 2008-09 seasons.
In May 2014, Sun was banned for three months by the Chinese Swimming Association after he tested positive for trimetazidine, a drug that was banned only four months earlier and classified as a banned stimulant at the time by the World Anti-Doping Agency. He said that a doctor prescribed the drug to him to treat heart palpitations, a condition he has suffered since 2008. WADA, after reviewing the full case file, announced that they would not challenge the CSA's decision to impose a three-month sanction. Since Sun's ban, WADA has reclassified trimetazidine from an S6 stimulant to an S4 hormone and metabolic modulator.
In September 2018, Sun was involved in an incident during an out-of-competition anti-doping test at his home, during which he and his staff smashed open a container of blood sample vials with a hammer because he had believed that the testing personnel did not have proper credentials. Following an investigation, the international governing body for swimming, FINA, concluded that Sun did not commit an anti-doping rule violation. WADA disagreed with FINA's decision and lodged an appeal with the Court of Arbitration for Sport, which accepted the case and held a public hearing in November 2019. On 28 February 2020, CAS delivered its findings, overturning FINA's decision and banning Sun for eight years for tampering with the doping control process. The CAS clarified that Sun would not be stripped of any of his medals because "doping tests performed on the Athlete shortly before and after the aborted doping control in September 2018 were negative" and "in the absence of any evidence that the Athlete may have engaged in doping activity since 4 September 2018, including on the occasion of the FINA World Championships in Gwangju, South Korea in July 2019, the results achieved by the Athlete in the period prior to the CAS award being issued should not be disqualified."
Early life
Sun was born on 1 December 1991 in Hangzhou, Zhejiang, China. He was named after his parents' surnames. Sun is an only child, and his family is athletic. His father, Sun Quanhong, was a basketball player for Anhui Tigong and is also tall. His mother, Yang Ming, was a volleyball player for Zhejiang and is a sports coach. Sun started swimming in 1998, and his potential was recognised by a teacher at Jinglun Sports School in Hangzhou.Career
2007–2011: Early career
Sun made his international debut at the 2007 World Championships in Melbourne, Australia. He finished 32nd in the 400 metre freestyle and 23rd in the 800 metre freestyle. In early 2008, he competed at the "Good Luck Beijing" China Open, a test event for the 2008 Summer Olympics. He finished 2nd in the 400 metre freestyle with a time of 3:49.34. At the Olympics, Sun, aged 16, finished 28th in the 400 metre freestyle, unable to reach the final. He later came 7th in the qualifying heats of the 1500 metre freestyle, reaching the final, where he finished last. Sun rebounded the following year at the 2009 World Championships, where he won his first international medal, a bronze, in the 1500 metre freestyle with a time of 14:46.84. He finished 18th in the 400 metre freestyle with a time of 3:47.51.Sun achieved further success during the 2010 Asian Games. He won gold medals in the 1500 metre freestyle and the 4 × 200 metre freestyle relay, and silver medals in the 200 metre and 400 metre freestyle. His 1500-metre freestyle time of 14:35.43 was a new Asian record and the second-fastest time in history, behind Grant Hackett, whose record Sun would surpass the following year. Sun was subsequently named Rookie of the Year at the 2010 China Central Television Sports Awards.
On the first day of competition at the 2011 World Championships in Shanghai, Sun came 2nd in the 400 metre freestyle with a time of 3:43.24, 1.2 seconds behind South Korean Park Tae-hwan. Three days later, Sun won his first World Championship title in the 800 metre freestyle with a time of 7:38.57. After a day of rest, he swam the anchor leg in the 4 × 200 metre freestyle relay, helping the Chinese team win bronze. The last day of competition, Sun competed in the 1500 metre freestyle. He won the race with a time of 14:34.14, ten seconds ahead of the rest of the competition. At age 19, Sun beat Hackett's world record of 14:34.56, which had stood for ten years. This was the longest-held world record in swimming and the only men's swimming world record not to have been beaten during the techsuit era.
2012: Breakthrough at the Olympics
For the 2012 Summer Olympics, Sun was considered a favourite in the 400 metre and 1500 metre freestyle, as well as a contender in the 200 metre freestyle. In his first event, the 400 metre freestyle, he won the gold medal with a time of 3:40.14, breaking the Olympic record previously held by Ian Thorpe and becoming the first Chinese male swimmer to win a gold medal at the Olympics. His time was also the third fastest in history, 0.07 seconds away from the world record, and setting a new Asian record. After a day of recuperating, Sun competed in the 200 metre freestyle. He won a silver medal in the final, tying with Park Tae-hwan with a time of 1:44.93, a new national record. The following day, Sun swam the anchor leg in the 4 × 200 metre freestyle relay to help the Chinese team win bronze, China's first Olympic medal in a men's relay event.After the relay, Sun did not return to the pool until the last day of competition to compete in his strongest event, the 1500 metre freestyle. He had qualified for the final with the fastest time. At the initial line-up on the starting blocks, a step-down command was issued because of noise from the crowd, but instead of stepping back, Sun reacted by diving in. The officials ruled the early dive was the result of crowd noise and did not constitute a false start, and Sun was allowed to continue in the competition. He went on to win the race with a time of 14:31.02, breaking his own world record by over three seconds. He finished over eight seconds ahead of second-place finisher, Canadian Ryan Cochrane. With two gold medals and a team bronze medal, Sun became the most decorated Chinese male swimmer in Olympic history, and the first swimmer to win the 400/1500 double since Vladimir Salnikov at the 1980 Moscow Olympics. Sun completed the last 50 metres of the race in 25.68 seconds, nearly two seconds faster than Cochrane.
2013: Continued success
From 28 July to 4 August 2013, Sun competed at the World Championships. On the first day of competition, he won gold in the 400 metre freestyle with a time of 3:41.59. It was nearly 1.5 seconds off his Olympic-winning time from the previous year, but he was still 3.23 seconds ahead of runner-up Kosuke Hagino. Two days later, Sun retained his title in the 800 metre freestyle with a time of 7:41.36. It was his second gold medal in the Championship and the 100th gold medal won by China in World Aquatics Championships' history.On the sixth day of competition, Sun was tasked with swimming the anchor leg for the 4 × 200 metre freestyle relay. China barely qualified for the final in eighth place. Going into the last leg of the race, China was in fifth place, over two seconds behind France and Japan, but Sun was able to overtake both teams in the end for a final time of 1:43.16. This was the second-fastest split time in history and 1.82 seconds faster than the other 31 swimmers in the final, including Ryan Lochte and Yannick Agnel. Accounting for the relay exchange advantage, it was still over a second faster than his flat start time of 1:44.93.
On the final day of the competition, Sun successfully defended his title in the 1500 metre freestyle. He finished with a time of 14:41.15, beating runner-up Ryan Cochrane by 1.33 seconds. This result made Sun the second swimmer in history, after Grant Hackett, to win gold medals in all three long-distance freestyle events—400, 800, and 1500 metre—in a single World Championships.
One month later, Sun competed in the 2013 National Games of China. Aiming to become the first man to win seven gold medals at a single championship, he added to his range the 100 metre freestyle, an event typically reserved for sprinters. With the games holding the same schedule as the Olympics, he competed first in the 400 metre freestyle, winning in 3:43.68—over a second ahead of Hao Yun. The following day, Sun won the 4 × 100 metre freestyle relay, swimming the anchor leg in 48.14 seconds. He followed these performances the next day by setting a new Asian record in the 200 metre freestyle with a time of 1:44.47, about half a second faster than his time in London. The following day, he won bronze in the 100 metre freestyle, finishing with a time of 48.94 seconds, his first time finishing under 49 seconds.
2014: Doping ban and Asian Games
In May 2014, the Chinese Swimming Association banned Sun for three months after he tested positive for trimetazidine, a drug that was banned four months earlier and classified as a stimulant at the time by the World Anti-Doping Agency. Sun said that a doctor prescribed the drug to treat heart palpitations and was unaware that it had been newly added to the banned substances list. WADA chose not to pursue the case after an investigation.Following his doping ban, Sun made a comeback in his first post-suspension event in the 2014 China Spring Nationals, where he won a gold medal in the 200 metre freestyle. At the 2014 Asian Games, Sun participated in the 200, 400, and 1500 metre freestyle events. He won silver in the 200 metre freestyle, finishing behind Kosuke Hagino. In the 400 metre freestyle, he came 1st with a time of 3:43.23, which was 1.25 seconds ahead of runner-up Hagino. Leading from start to finish, Sun won gold in the 1500 metre freestyle. He finished with a time of 14:49.75, over five seconds ahead of runner-up Kohei Yamamoto. Sun also participated in the 4 × 100 metre freestyle relay, helping China win gold with an overall time of 3:13.17, setting a new Asian Record in the event.
2015 World Championships
At the 2015 World Championships, Sun won silver in the 200 metre freestyle with a time of 1:45.20, finishing 0.06 seconds behind James Guy. In the 400 metre freestyle, he won gold with a time of 3:42.58, finishing 1.17 seconds ahead of Guy. He finished 1st in the 800 metre freestyle with a time of 7:39.96, which was 0.85 seconds ahead of runner-up Gregorio Paltrinieri.In the 1500 metre freestyle, where he was the two-time defending champion, Sun withdrew from the competition, later citing heart problems during a warm-up. "I feel very sorry that I couldn't be present for the 1500m", Sun told reporters. "I didn't feel good in my heart. Today I felt really uncomfortable at the pool during my warm-up and I had to give up the idea of competing. I feel really sorry about that."
At the World Championships, Sun was accused by Brazilian coaches of assaulting one of their female swimmers, Larissa Oliveira. Brazil team spokeswoman Eliana Alves told the Associated Press that there was "contact" between Sun and Oliveira, "but it was not a fight". Swimming's world governing body, FINA, later cleared Sun of any wrongdoing. FINA executive director Cornel Marculescu explained that the altercation that led to a complaint against Sun was due to congestion in the warm-up pool, and did not warrant further action. According to Marculescu, there were over 1,000 swimmers present, so the preparation pool became very crowded.
2016: Historic first at the Olympics
In June 2016, Sun competed at the Arena Pro Swim Series finale in Santa Clara, California. He won the 200 metre freestyle event with a time of 1:44.82, giving him 1st in the world ranks.At the 2016 Summer Olympics, Sun won the 200 metre freestyle with a time of 1:44.65, finishing 0.55 seconds ahead of runner-up Chad le Clos. It was Sun's first major international title in this event, and he became the first Chinese athlete to win a gold medal in this event. He won a silver medal in the 400 metre freestyle with a time of 3:41.68, finishing 0.13 seconds behind Mack Horton of Australia. Sun finished 16th in the qualifying heats of the 1500 metre freestyle, clocking in at 15:01.97. With his 200-metre freestyle gold medal and his 400 and 1500 metre freestyle gold medals from the 2012 Summer Olympics, Sun became the first swimmer in history to win Olympic gold medals in the 200, 400, and 1500 metre freestyle events.
The lead-up to the 400 metre freestyle was marred by controversy. Sun was accused of splashing water into rival Horton's face during practice. Horton accused Sun of attempting to distract him. Sun and Xu Qi, the Chinese swim team manager, denied the allegations and said it must have been a misunderstanding. Horton responded by accusing Sun of being a "drug cheat", in reference to his 2014 suspension. Horton's social media pages garnered negative criticism from Chinese fans, with many calling the Australian as a racist, a "snake", and a "disrespectful person". The Chinese Swimming Association requested an apology for the allegation, stating that Horton's claims "have greatly damaged sporting ties between China and Australia, and damaged the image of Australian athletes"; the request was turned down. Further controversy arose when the Global Times, a Chinese newspaper, printed critical editorials about Australia. An op-ed piece in another Chinese newspaper, Changjiang Daily, called for calm and indicated that the dispute was only between the two athletes and should not become a conflict between the two countries.
2017–18: Asian Games success and testing incident
In 2017, Sun competed at the World Championships. In the 200 metre freestyle, Sun won gold with a time of 1:44.39, setting a new Asian and Chinese national record. In the 400 metre freestyle, he won gold with a time of 3:41.38, finishing 2.47 seconds ahead of runner-up Mack Horton and winning his third straight 400 metre freestyle world title. Sun finished 5th in the 800 metre freestyle, failing to defend his title. He withdrew from the 1500 metre freestyle.In August 2018, Sun competed in every freestyle event from the 200 to the 1500 metre freestyle at the Asian Games. He also competed in the 4 × 100 and 4 × 200 metre freestyle relay events. In the 200 metre freestyle, Sun won gold with a time of 1:45.43. He finished 1st in the 400 metre freestyle with a time of 3:42.92, over four seconds ahead of runner-up Naito Ehara. By beating Horton's time of 3:43.76 from the 2018 Commonwealth Games, Sun became the number-one swimmer in the world for that event for 2018. In the men's 800 metre freestyle, which was introduced to the Asian Games for the first time, he won gold with a time of 7:48.36. In the 1500 metre freestyle, he finished 1st with a time of 14:58.53, beating runner-up Nguyễn Huy Hoàng by over three seconds. It was the first time Sun swam the event within 15 minutes since the 2014 Asian Games, and his third consecutive Asian Games title in the 1500 metre freestyle. Representing China, Sun helped his team finish second in the 4 × 100 metre freestyle relay with an overall time of 3:13.29, behind Japan's time of 3:12.68. In the 4 × 200 metre freestyle relay, he helped China win silver with an overall time of 7:05.45, behind Japan's 7:05.17.
In September 2018, Sun experienced an out-of-competition test at his home. Following investigations, FINA's inquiry panel ultimately concluded that "Mr. Sun Yang has not committed an anti-doping rule violation", which FINA accepted. In December at the 2018 FINA World Swimming Championships, Sun participated in the 4 × 200 metre freestyle relay, helping China win bronze.
2019 World Championships
At the 2019 World Championships, Sun finished 2nd behind Danas Rapšys in the 200 metre freestyle. After the race was over, Rapšys was disqualified for a false start, giving Sun the gold and his third straight medal in the event at the World Championships. In the 400 metre freestyle, Sun won gold with a time of 3:42.44, finishing 0.73 seconds ahead of runner-up Horton and earning his fourth consecutive title in this event.Sun clashed with Duncan Scott during the 200 metre freestyle presentation. Both the British and Australian camps had been critical about Sun's actions the year prior. Scott refused to share the podium with Sun, and neither competitor shook hands, after which Sun could be seen gesturing and shouting at Scott. In a similar incident a few days earlier, Australian swimmer Mack Horton had also refused to share the podium with Sun. Horton was given an official warning by the sport's organising body, FINA. Following the medal ceremonies, Horton, Scott, and Sun were served letters by FINA, warning them about their behaviour. In a statement, FINA said: "While FINA respects the principle of freedom of speech, it has to be conducted in the right context ... use FINA events to make personal statements or gestures".
Despite Horton not having any evidence of cheating against Sun Yang, except for the circumstantial FINA and later CAS ruling against Sun on unrelated charges, he claims to “know” that Sun Yang was doping, and says his stance is not personal or due to national prejudice.
Doping allegation and controversies
2014 ban
In May 2014, Sun was banned for three months by the Chinese Swimming Association after he tested positive for trimetazidine, a drug that was banned four months earlier and classified as a stimulant at the time by the World Anti-Doping Agency. The substance was at the time prohibited in competition only; the ingestion of trimetazidine by an athlete out of competition "is inconsequential" and constitutes illicit behaviour only if the athlete later participates in competition before the substance clears their system. Sun said that a doctor prescribed the drug to treat heart palpitations, a condition he has suffered since 2008, and that he was unaware that it had been newly added to the banned substances list. He was eligible to file a medical exception to use the drug for his heart condition, but he did not do so.The World Anti-Doping Agency admonished the Chinese Swimming Association for tardiness in reporting the failed test and the subsequent ban until after it had been served, meaning that Sun never missed a major event. FINA's handling of the case was criticized for allegedly "protect one of the sport's biggest stars in a key market". According to Swimming World Magazine, Sun's mother Yang Ming said in a now-deleted social media post that the Chinese Swimming Association attempted to hide Sun's three-month suspension in 2014.
In January 2015, WADA reclassified trimetazidine from "stimulant" to "modulator of cardiac metabolism", prohibiting its use out of competition in addition to the previous prohibition of use in competition. It remains a banned substance as of 2020. WADA criticised the CSA for its lateness in reporting the failed test result and subsequent ban until after it had been served. WADA, which had a right to petition if it believes a sanction to be lenient, chose not to take further action after reviewing the case. CHINADA deputy director Zhao Jia said that "Sun proved with sufficient evidence that he did not intend to cheat, which helped reduce his ban to three months", but he was stripped of his win in the 1500 metre freestyle at the 2014 Chinese nationals. One Australian writer opined that the punishment was lenient, but pointed out that Yang was not found to have doped intentionally. After the ban, Swimming Australia ordered coach Denis Cotterell to stop working with Sun, but Cotterell continued coaching him.
2018 testing incident and 2020 ban
On the night of 4 September 2018, three anti-doping testers arrived at Sun's house to administer an out-of-competition blood and urine test. After giving blood, he was escorted to the bathroom by a doping control assistant to be observed passing urine. Sun noticed the DCA had been taking pictures of him and requested his accreditations, which were not provided. The DCA later said he was a construction worker.After calling his coach, his lawyer, and the head of the Chinese swimming delegation, Sun did not sign the testing paperwork. According to evidence presented to the Court of Arbitration for Sport, he offered to wait for a properly accredited team, but was declined. The anti-doping testers later testified to the CAS that Sun and his entourage intimidated them.
Around 3:00 am, Sun's camp called the deputy director of the Zhejiang Anti-Doping Centre, asking how to dispose of the blood sample. His team then directed his security guard to smash the case containing the vials to break the chain of custody, so the sample could not be tested.
The official report from the FINA inquiry dated 3 January 2019 stated the following:
The inquiry panel concluded that "Mr. Sun Yang has not committed an anti-doping rule violation", which FINA accepted. WADA disagreed with FINA's decision and appealed to the Court of Arbitration for Sport, which accepted the case. Sun's lawyers told the Associated Press he requested that his CAS hearing to be public and "fully transparent to clear his name". FINA supported a move to stop the CAS hearing.
In January 2019, The Sunday Times published an article reporting that Sun and his team smashed vials of blood samples with a hammer in front of anti-doping testers and that he may face a lifetime ban. Sun's lawyers decided to take legal action against The Sunday Times, denouncing all claims made in the report.
CAS issued a report on 20 August 2019, stating the appeal hearing brought by WADA against Sun and FINA in September had been postponed due to a party's unexpected personal circumstances. It was announced that the hearing date would be rescheduled and made open to the public, including to the media, as requested. WADA requested for a ban of between two and eight years according to a later media release from CAS.
A year before the 2018 testing incident, Sun had heated tensions with the same unnamed female doping control officer who presided over his sample collection in the 2018 incident. In 2017, the officer was a doping control assistant in training to become an officer. Sun wrote that the DCA "lacked proper accreditation and also lacked authorization to perform her assigned role". The report covering the 2017 disagreements of Sun and his testers did not clearly indicate that the quarrels were ever resolved.
On 15 November 2019, the public hearing was held at CAS in Montreux, Switzerland. It was live streamed and released online. The hearing was affected by translation issues throughout the day. According to Time, the translation issues made it unclear how much of the testimony and questions were understood, and both judges and lawyers expressed frustration. The transcript of Sun's final remarks in Chinese during the public hearing was posted online by Sun himself after the hearing.
On 18 November, the DCA, who remained anonymous and did not appear at the hearing, said that he was a construction worker rather than a trained doping tester. According to Xinhua News Agency, he had submitted his written testimony in Chinese to CAS and WADA several days before the hearing. WADA's lead counsel Richard Young referred to "concerns over intimidation and protection issues", while during cross-examination of witnesses WADA co-counsel Brent Rychener highlighted the threats and warnings made by members of Sun's entourage to the testing officers, including exchanges involving the swimmer's mother, Dr. Ba Zhen, and Dr. Han Zhaoqi. The WADA provided witness statements from the DCO and the BCA, indicating that they had been contacted by Sun's entourage and were "concerned for their physical and economic well-being, and for the well-being of their family members". They indicated they were "fearful that, if they would agree to testify in this proceeding, they would suffer significant retaliation in some form from and/or his entourage and supporters". WADA further noted if they had not issued an order, there would be little or no chance that IDTM's Sample Collection Personnel would be willing to testify under such threats.
On 28 February 2020, a panel of three senior judges at CAS unanimously found Sun guilty of refusing to co-operate with sample testers and banned him from swimming until February 2028. The eight year ban, the maximum CAS can hand out, was imposed because it was his second offence after his 2014 suspension.
The panel said:
WADA issued a statement welcoming the verdict, saying that the "CAS ruling confirms those concerns" about the original FINA decision that seemed to be incorrect under the World Anti-Doping Code. The ban rules Sun out for the 2020 Tokyo Olympics and "effectively ends his career". The only remaining possibility for Sun and his legal team is to appeal the decision to the Swiss Federal Court, but only on narrow procedural grounds. The court ruled that Sun can maintain the two world titles he won in South Korea.
Soon after the verdict was announced, Sun told Xinhua News Agency he would definitely appeal the "unfair" ban. Some analysts said the hearing was marred by severe translation problems, conflict of interest, and bias. One Australian sports writer suggested that there was hypocrisy and double standards against Sun, with an actual "absence of evidence" around doping activity.
When the verdict was announced, Chinese online users continued to defend Sun while insulting his chief rival Mack Horton. An unnamed analyst noted that the harassment against Horton—which had been ongoing since 2016—was likely "state-orchestrated" on Sun's behalf, saying: "the family's ordeal is believed to be well-organised and part of a systematic pattern of harassment and intimidation directed at perceived critics of China". This is not an amateur operation. The Hortons' story is very disturbing … It says something about the reach of foreign powers within Australia." After the release of the report from the CAS, public support for Sun dropped in mainland China. According to Jonathan White at SCMP, Chinese users bypassing China's Great Firewall to log onto Instagram apologized to Horton for the harassment, with statements that include "sometimes our Chinese could not get the truth, but most of us are kind and goodness person", criticizing Sun as "arrogant" and a "baby", and noted that "Sun deleted all of his post-verdict posts purporting to offer new 'evidence'".
Major achievements
In 2012, Sun became the first Chinese man to win an Olympic gold medal in swimming. He is the first male swimmer in history to earn Olympic and World Championship gold medals at every freestyle distance between 200 and 1500 metres. A three-time Olympic gold medallist and eleven-time world champion, Sun is the most decorated Chinese swimmer in history.Sun's major achievements include:
