BOSTON -- Left-hander Thomas Pomeranz had to leave the Red Sox's 9-6 win over the Yankees on Friday night with one out in the top of the fourth with back spasms, but he is hopeful he can make his next start on Wednesday in Cleveland.
"My back just tightened up on my lower right side. It happens sometimes," said Pomeranz. "My hip gets all jammed up and starts pulling on muscles back there. I should be fine in a couple of days, or tomorrow even."
That would be good news for the Red Sox, as Pomeranz has been the team's most consistent starter after Chris Sale, going 12-4 with a 3.31 ERA.
"Any time a guy comes out of the game, you're always concerned," said Red Sox manager John Farrell. "He did have this last year, when he first arrived here. So we've got to get the spasms calmed down. That's honestly where it is right now. We're not to the point where we don't think he'll make his next start, but the next two days will have a major impact on that."
Pomeranz grabbed his back after throwing a ball to Chase Headley and was removed from the game after conferring with a member of the training staff.
Brandon Workman came on in relief with a 2-0 count, and the walk to Headley was charged to Pomeranz.
The Red Sox had a 2-0 lead when Pomeranz exited.
