BOSTON -- Will Middlebrooks left Thursday's game against the Indians in the fifth inning due to what is being called low back spasms.
The third baseman was 0-2 on the night, striking out looking both times.
"Back started to tighten up throughout the course of tonight's game," John Farrell said after the Sox 12-3 loss. "This is unrelated to the rib injury that he was dealing with in the collision with the wall 10 days ago or so. In his last at-bat last night he felt- I think he slipped a little bit coming out of the box a little bit, but didn't mention any complaint prior to the game tonight. As things unfolded, the stiffness was there, and so he's day-to-day right now."
On the year, Middlebrooks is hitting just .201, but is tied for the team lead with eight home runs. In fact, of his 35 hits this season, 20 have gone for extra bases (12 doubles, eight home runs).
Pedro Ciriaco took over for Middlebrooks in the top of the 5th inning, after Middlebrooks struck out in the bottom of the 4th. Going into Thursday, Ciriaco was hittin just .184 with one home run and three RBI.
