Most diehard baseball fans know that Hardy has the honor of being the only player ever to pinch-hit for Ted Williams, but few know that his pinch-hit résumé goes well beyond this claim to immortality: he was the only player to pinch-hit for Carl Yastrzemski, Williams's replacement in left field, and also pinch-hit for Roger Maris.
Indians
Hardy spent two seasons, 1957–58, with the Indians farm team, the San Diego Padres, owned at the time by C. Arnholt Smith, founder and owner of San Diego's U.S. National Bank. A reserve for the majority of his career, he debuted with the Cleveland Indians in the 1958 season. On May 18, celebrating his 25th birthday, he pinch-hit for Roger Maris and belted his first major leaguehome run, a three-run blast off Billy Pierce, to lead Cleveland to a 7–4 victory over the Chicago White Sox.
Red Sox
Late in the 1960 season, Hardy was on the bench for the Boston Red Sox. Ted Williams, in the final days of his Hall of Fame career, fouled a ball off his foot in the first inning of a game on September 20. After he limped off the field, Hardy finished the at bat for him, becoming the only player ever to do so. Hardy lined into a double play. On September 28 at Fenway Park, in his final major league appearance, Williams hit his 521st and last home run offJack Fisher of the Baltimore Orioles. In the ninth inning, he was replaced by Hardy in left field. "They booed me all the way out and cheered him all the way in", Hardy later remembered. Then, on May 31, 1961, Hardy pinch-hit for rookie Carl Yastrzemski, making him the only player in major league history to go in for both future Hall of Famers. Hardy saw most action in 1962, posting career highs in games, at-bats, hits, runs, home runs and runs batted in, but hit for just a.215 average. On April 11, Hardy enjoyed another career highlight at Fenway Park when he broke up a scoreless pitching duel between Cleveland's Ron Taylor and Boston's Bill Monbouquette, hitting a 12th-inning walk-offgrand slam for a 4–0 Red Sox victory over the Indians.
Remaining career
On December 10, 1962, Hardy was traded to the Houston Colt.45s for another outfielder, Dick Williams, who eventually became Boston's manager, leading them to the 1967 American League pennant, and enjoyed a long Hall of Fame career as a manager. Hardy spent most of the remainder of his playing career at the Triple-A level, with brief appearances for Houston and Minnesota. On the last day of the 1967 season, the Twins lost a chance to clinch the American League pennant to the Red Sox, 6-2, at Fenway Park. With two outs in the 9th inning, Rich Rollinspinch hit for catcher Russ Nixon popping out to Rico Petrocelli for the last out of the game. Had Rollins reached base, Hardy would have pinch hit for Twins pitcher Mudcat Grant. Hardy managed in the Twins' farm system at the Class A level in 1968. In an eight-season career, Hardy was a.225 hitter with 17 home runs and 113 RBI in 433 games.
After baseball
With his baseball career behind him, Hardy worked for 20 years in the Denver Broncos' front office. As a player personnel director, he was the key figure in building the Orange Crush Defense in the 1970s. He was also with the Broncos when they went to Super Bowl XII in 1977. He now works for Steamboat Springs, Colorado.
