Phillies right-hander Roy Halladay pitched a perfect game on Saturday night against the Marlins. Halladay is just the 20th pitcher in baseball history to accomplish the feat, but he's only the second this month. Dallas Braden pitched one for the Athletics on May 9 against the Rays. Philadelphia defeated Florida 1-0 as Halladay recorded 11 strikeouts. The only run of the game came unearned in the third inning.
