OAKLAND -– Reliever Ryan Cook was diagnosed with a strained right forearm after he was forced to exit the A’s 6-4 loss to the Seattle Mariners on Wednesday afternoon.
Manager Bob Melvin, speaking briefly between games of a doubleheader, said he didn’t know how much time Cook might miss.
“Cook's a forearm strain and we're not sure (on a timetable),” Melvin said. “He said he felt it a little bit on the pitch before and a little more so on the next pitch.”
Cook left after throwing a slider to strike out Corey Hart in the top of the 10th, when Seattle scored twice to snap a tie and send the A’s to their sixth consecutive home defeat.
Drew Pomeranz is starting on the mound for Oakland in the second game, which was set to start at about 4:30 p.m.
Center fielder Coco Crisp is considered day to day and won’t play in the night cap after suffering a neck strain while making a catch and crashing hard into the outfield wall in the first game.
