Yankees' Pineda headed to DL with Grade 1 back strainThe Yankees' starter suffered the injury during a simulated game on Tuesday
Manager Joe Girardi was unaware of the specifics, but Yankees public relations informed the media of the MRI results shortly after the Yankees' 6-3 loss to the Mariners on Tuesday night.
Pineda felt the injury during a simulated game down in Tampa on Tuesday afternoon, pulling himself after one inning after feeling discomfort in the area of his right latissimus dorsi muscle. An MRI revealed the strain of the Teres major, a muscle between the scapula and the latissimus dorsi.
The injury will land Pineda on the disabled list, and general manager Brian Cashman told the media that the righty will be shut down for 10 days and likely be out for three-to-four weeks.
David Phelps is scheduled to start in the suspended Pineda's place Wednesday, and Girardi had said when giving the initial update on Pineda Tuesday afternoon that Phelps was likely to stay in the rotation if Pineda misses extended time.
