The back end of the Yankees' bullpen continues to slowly crumble.
David Robertson is the latest to hit the disabled list thanks to an oblique strain on his left side. Manager Joe Girardi said before Tuesday's game that they will take the rehab slowly.
"We don't think it's too severe, but it's hard to tell. Obliques can be tricky," Girardi told reporters. "We expect him not to pick up a baseball for probably seven to 10 days and then we'll see where we are after that."

Rafael Soriano came in Monday night in a save situation, prompting questions about Robertson's availability. He had not pitched the night before either. Girardi said after the game that had it been a save situation, Robertson would not have pitched Sunday either.
The injury apparently happened last Friday when he pitched in a non-save situation against the Mariners. That was his first outing since blowing his second save opportunity after replacing Marian Rivera.
Of course, Robertson moved into the closer's role when Rivera tore his ACL in a pre-game accident in Kansas City. He will miss the rest of the season.
Soriano has significant experience as a closer in both Atlanta and Tampa Bay and will get the majority of the saves while Robertson is out.
