Roy Halladay of the Philadelphia Phillies pitched the 20th perfect game in Major League Baseball history Saturday.
The right-hander retired all 27 Florida Marlins batters he faced in a 1-0 victory in Miami. He struck out 11. See the boxscore at SI.com
Halladay, 33, came into the game with a 6-3 won-loss record and a 2.22 earned-run average, according to MLB.com.
Although the feat is among the rarest in baseball, 2010 will go down as the first year in the modern era in which a perfect game has been thrown twice in the same season. The Oakland Athletics' Dallas Braden was perfect against the Tampa Bay Rays on May 9.
