Longoria, who entered the game with three home runs in his previous two games, played defense in the fifth inning. However, he did not return to play the field in the sixth. Rookie Richie Shaffer finished the game at third base.
"Just felt like I really couldn't get a good grip on the ball," Longoria said. "... It's OK, it just continued to get tight throughout the course of the game. That last inning I was in there, I actually felt like I was a liability.
"I was trying to throw the ball across the infield, and [my forearm] was real tight. I think it's just day to day. It hit me right in the muscle. No need for an X-ray, there's no break. I hope I'm in there tomorrow."
