In the Yankees 4-0 victory, Wells retired all 27 batters he faced and became the thirteenth pitcher in major-league history to record a perfect game.
While Don Larsen tossed a perfect game in the 1956 Fall Classic, Wells became the first Yankee in the regular season to pull off the feat.
Wells threw nine pitches in the first frame, 13 in the second stanza, and struck out the side in the third inning on 19 pitches.
Cruising along into the seventh inning, Wells kept it going as Tino Martinez beat Brent Gates to first base on a hot smash grounder.
