The New York Yankees have placed closer David Robertson on the 15-day disabled list with a strained oblique muscle.

Robertson, who was named closer by manager Joe Girardi after the knee injury to Mariano Rivera, had been unavailable to the team since May 11th. Rafael Soriano closed out the game last night in Baltimore to record his second save of the season. He has 92 career saves in 112 chances, with 45 of those coming in 2010 for the Tampa Bay Rays.

Robertson struggled in his second save opportunity of the season against the Rays on May 9th, allowing three hits and four earned runs, with Matt Joyce doing most of the damage with a three-run shot in the ninth. He appeared in the game May 11th against the Mariners, recorded both outs, his final appearance before the injury was revealed before the game last night.

The 2011 All-Star posted a 2.8 fWAR last season,  with a 1.84 FIB, allowing just one home run in 66.2 innings.

New York recalled right-hander Cody Eppley from Triple-A Scranton/Wilkes-Barre to take his place on the roster.
