The first perfect game of the season came this afternoon in Seattle, as Philip Humber of the White Sox went the distance without allowing a baserunner. It came down to the wire when Brendan Ryan, the 27th hitter, worked the count to 3-2. After fouling a ball off, he swung at a ball in the dirt that got by the catcher. Ryan appeared to have checked his swing and didn't run to first, so A.J. Pierzynski retrieved the ball and threw him out with little trouble.
There wasn't a good enough replay to see if Ryan fully swung, but the ump called it a strike nonetheless.
