The Detroit Tigers placed a pair of ailing pitchers — starter Anibal Sanchez and reliever Joakim Soria — on the disabled list Sunday.

Sanchez is expected to miss three to four weeks with a strain of his right pectoralis major that took him out of his last start Friday, and will be replaced in the starting rotation, at least initially by Robbie Ray.

Soria injured his left oblique in Saturday’s game.

The Tigers have not yet announced who will fill Soria’s roster spot, with the options including Ian Krol, Kevin Whelan and recent acquisition Jim Johnson, according to general manager Dave Dombrowski.
