Did Roy Halladay pitch a perfect game?

The Philadelphia Phillies’ Roy Halladay pitched the twentieth perfect game in Major League Baseball history on May 29, 2010, against the Florida Marlins at Sun Life Stadium.

At 7:17 p.m., Halladay threw a called strike to Chris Coghlan on a 92 mph fastball on the outside corner. He threw 19 pitches in the first inning, his most of the night, and no other inning required more than 12 except the seventh.

He threw 115 pitches, 72 of which were strikes. Halladay worked his way out of seven three-ball counts and six full counts, crediting his success to the effectiveness of his sinker.  Sinkers accounted for four of his 11 strikeouts.

Halladay became the Phillies’ 10th no-hitter pitcher; Jim Bunning’s perfect game in 1964 was the only other time a Phillies pitcher threw a perfect game.

Furthermore, this was the eighth perfect game in National League history, with Randy Johnson’s perfect game coming in 2004.

This was the first time in modern history that two pitchers (the other being Dallas Braden of the Oakland Athletics) threw perfect games in the same month, and that multiple perfect games were achieved in the same season.
