Roy Halladay, American baseball player (born 1977)

Harry Leroy Halladay III was an American professional baseball pitcher who played in Major League Baseball (MLB) for the Toronto Blue Jays and Philadelphia Phillies between 1998 and 2013. His nickname, "Doc", coined by Toronto Blue Jays announcer Tom Cheek, was a reference to Wild West gunslinger Doc Holliday. His lasting durability allowed him to lead the league in complete games seven times, the most of any pitcher whose career began after 1945. He also led the league in strikeout-to-walk ratio five times and innings pitched four times. An eight-time All-Star, Halladay was one of the most dominant pitchers of his era and is regarded as one of the greatest pitchers of all time.
