John Hiller grew up in Scarborough, Ontario and was a former left-handed relief pitcher in Major League Baseball who played his entire career with the Detroit Tigers.
After suffering a heart attack in 1971, he returned to the team and recorded 38 saves in 1973 – a major league record until 1983, and a team record until 2000. He also set an American League record by winning 17 games in relief, against 14 losses, in 1974 which was later equalled by Bill Campbell who went 17-5 in 1976. His 125 career saves ranked fourth in AL history and were the seventh most among all left-handers when he retired, standing as a team record until 1993. His 545 career games pitched ranked ninth among AL left-handers at the end of his career, and remain the Tigers franchise record.
He was inducted into the Canadian Baseball Hall of Fame in 1985, and into Canada's Sports Hall of Fame in 1999.
