Infielder Curtis Mead, 25, acquired from the Washington Nationals last week, left his first game with the Boston Red Sox on Monday after being hit on the left wrist by a pitch in the fourth inning of a 4-2 victory over the Athletics at Sutter Health Park.

Mead struck out looking in his first at-bat and was struck on the wrist by A's starter Jack Perkins in the fourth. He tried to shake off the pain but left after being checked by the trainer. The club announced a left wrist contusion; X-rays were negative. "I felt OK. Squeezing my hand feels OK. Just a little bit of pain rotating," Mead said. "We were able to get an X-ray, and everything looked OK. So, I'm hopeful that I will feel better tomorrow morning, and that it won't be a problem."

The Red Sox acquired Mead on Saturday in a trade that sent left-hander Connelly Early to Washington. Mead admitted disappointment: "I was super disappointed... I wanted to come here and help the team, and I wanted to play." Mead is hitting .253 with 17 home runs and 48 RBIs this season. He was replaced by Anthony Seigler, who went 0-for-2.
