BALTIMORE -- A's left-hander Drew Pomeranz departed Friday's marathon with the Orioles with one out in the 13th inning because of forearm tightness.
Pomeranz -- relieved by Aaron Brooks, who surrendered a two-run walk-off homer to Manny Machado in the 8-6 loss -- believes the issue to be minor.
"It started cramping up on me towards the end of my outing," Pomeranz said.
