This perfecto was the first this year and is part of a recent trend of no-hitters. Humber retired all 27 Seattle Mariners batters in a 4-0 win.
The last pitcher to throw a perfect game was Roy Halladay on May 29, 2010. Halladay accomplished his perfect game against the then-Florida Marlins. Mark Buehrle of the White Sox tossed a perfect game in July of 2009.
Humber's feat marked the first time that he went the distance in any major league game. His previous high was 7.2 innings. In April of 2011, Humber had a no-hit bid through 6.1 innings against the New York Yankees.
Humber has dealt with some injuries since being drafted third overall by the New York Mets in 2004. His most significant injury to date was when he required Tommy John surgery in 2005.
Humber was picked up by the White Sox in January of 2011.
