Athletics pitcher Drew Pomeranz worked just one of 12 innings in Thursday's game against the Mariners, but that was enough for him to earn his first win of the season in a 3-2, 12-inning victory.

Pomeranz worked a silent top of the 12th, retiring the Mariners in order on 15 pitches, with one groundball and two flyball outs. Coco Crisp gave Pomeranz the win with a walk-off home run in the bottom half of the inning.

Pomeranz is working out of the bullpen for the Athletics, after spending much of his career as a starter. He has one strikeout and two walks in two hitless innings so far.
