Red Sox's Masataka Yoshida: Begins rehab assignment

Yoshida (thumb) started as the designated hitter and went 1-for-4 with a run scored in a rehab game for Triple-A Worcester on Saturday.

Yoshida played the first of two rehab games as the DH for Worcester and said that he felt no pain coming out of either contest, Julian McWilliams of The Boston Globe reports. He'll serve as Worcester's DH again Sunday, and the Red Sox hope to have him back from the 10-day injured list by the end of the week.
