Strong began his broadcasting career while in high school at Lake Oswego High School, where he founded Laker Broadcasting. Strong created audio broadcasts of LOHS football and basketball games beginning in 2002. While attending School of Journalism and Communication at the University of Oregon, Strong worked at 750 KXL in Portland and was active at Oregon's campus station, KWVA. Strong continued his play-by-play work by broadcasting University of Oregon women's soccer, softball, and women's lacrosse. He also served as play-by-play voice for the Eugene Generals Junior Hockey team in 2005-06. Strong's first full-time broadcast job came at Portland's KXL radio and, later, 750 AM "The Game" in 2008. Strong produced "The Bald Faced Truth" radio show and also hosted a daily evening radio show called "Strong at Night" for the station. In 2010, Strong appeared on FSN Northwest as a play-by-play announcer for the Portland Timbers and in 2011 became the regular play-by-play announcer for Timbers broadcasts. Strong was a regular commentator on Europa League games for Fox Soccer, notably calling the 2013 Europa League final between Chelsea and Benfica. After the 2012-2013 season, he moved to NBC Sports to cover Major League Soccer and English Premier League football. Following NBC's loss of Major League Soccer coverage to Fox Sports in 2014, it was announced that Strong was moving full-time to Fox Sports to head the Major League Soccer, and Women's World Cup coverage. Strong was previously working part-time for Fox when he was not obligated to his NBC duties. In 2015, Strong also began to serve as the lead play-by-play voice for most United States men's national soccer team matches broadcast on FOX or Fox Sports 1, because of a new television contract between U.S. Soccer, Fox Sports, and ESPN. Brad Friedel joined him as the lead color commentator for these matches. He and lead color commentator Stuart Holden called the Fox broadcast of the 2018 FIFA World Cup, including the final. Strong's signature calls are "This one finishes " at the completion of every match and, at the end of every half, "45 minutes down, 45 to go" with the first part of the catchphrase building up to the outburst of the second.
In 2013, Strong was named Oregon Sportscaster of the Year by the National Sportscasters and Sportswriters Association. In 2011, he was awarded Major League Soccer’s Broadcast Call of the Year for his play-by-play call of midfielder Darlington Nagbe’s goal against Sporting Kansas City on July 2, 2011 at Jeld-Wen Field in Portland. Strong’s call has been viewed nearly two million times on YouTube.com and following the season was named the Timbers’ 2011 Play of the Year.
