NEW YORK (AP) — Joba Chamberlain has been placed on the 15-day disabled list with a stiff elbow, leaving the New York Yankees short two setup men in the bullpen.

Rafael Soriano also is sidelined, with inflammation in his right elbow, and is not expected back until perhaps the All-Star break. David Robertson is likely to assume the eighth-inning role as Mariano Rivera’s primary setup man, and manager Joe Girardi says he’ll look to mix and match in the seventh.

In other news, first baseman Mark Teixeira was back in the lineup Wednesday night after leaving Tuesday’s series opener against Boston when he was hit on the right kneecap by a first-inning pitch from Jon Lester. But catcher Russell Martin was out because his back locked up the night before.
