Harry Leroy "Roy" Halladay III (May 14, 1977 – November 7, 2017), was an American professional baseball player who pitched 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.
Halladay was chosen by the Blue Jays with their first selection in the 1995 MLB draft and was the 17th overall pick.
He played for the team from 1998 through 2009.
After being traded to Philadelphia in 2009, Halladay pitched for the Phillies from 2010 to 2013.
He was known for his ability to pitch effectively deep into games and, at the time of his retirement, was the active major league leader in complete games with 67, including 20 shutouts.On May 29, 2010, Halladay pitched the 20th perfect game in major league baseball history, beating the Florida Marlins by a score of 1–0.
On October 6, 2010, in his first postseason start, Halladay threw the second no-hitter in MLB postseason history (Don Larsen's perfect game in the 1956 World Series being the first) against the Cincinnati Reds in Game 1 of the 2010 NLDS.
This feat made Halladay the fifth pitcher in major league history (and the first since Nolan Ryan in 1973) to throw multiple no-hitters in the same calendar year (including the postseason).
During the 2012 season, he became the 67th pitcher to record 2,000 career strikeouts.
Halladay was also one of six pitchers in MLB history to win the Cy Young Award in both the American and National Leagues.
On November 7, 2017, Halladay died when his ICON A5 amphibious plane crashed into the Gulf of Mexico off the coast of Florida.
The Blue Jays organization posthumously retired his number 32 on March 29, 2018.
Halladay was announced as an inductee to the National Baseball Hall of Fame on January 22, 2019; he is the first posthumously-elected player since Deacon White in 2013 and the first elected by the BBWAA since Roberto Clemente in 1973.
