BALTIMORE -- Coco Crisp left Saturday's game prior to the bottom of the eighth inning due to tightness in his left hamstring, A's manager Bob Melvin said.
"We'll see how he is tomorrow," Melvin said. "[He is] day to day."
Crisp was 0-for-4 with a strikeout before he was removed.
Jonny Gomes replaced Crisp in the lineup and played left, while Yoenis Cespedes took Crisp's place in center.
In the eighth inning of Friday's game, Crisp was seen flexing his left hamstring after charging in to make a catch on a shallow fly off the bat of O's second baseman Omar Quintanilla.
Crisp remained in the game Friday, finishing 2-for-5.
