Roy Halladay played in Major League Baseball for the Toronto Blue Jays and Philadelphia Phillies between 1998 and 2013. His nickname, "Doc", was coined by Toronto Blue Jays announcer Tom Cheek, and was a reference to Wild West gunslinger Doc Holliday. An eight-time All-Star, Halladay was one of the most dominant pitchers of his era. Known for his outstanding durability, he led 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. He was elected to the Baseball Hall of Fame in January, 2019.
