Athletics starter Scott Kazmir left Sunday’s start against the Mariners after six innings with triceps tightness, Susan Slusser of the San Francisco Chronicle reports. Kazmir blanked the Mariners on two hits and struck out nine without issuing a walk.
Kazmir battled triceps tightness during the spring, so it’s nothing new for him. The lefty even wanted to go back out for the seventh inning, but Bob Melvin opted to go to his bullpen to be cautious with his pitcher. A scout noticed that Kazmir’s velocity dropped in his final inning and that he was wiggling his fingers.
