Stanton, who has been on the IL since April 1 with a strained left bicep, sustained a left shoulder injury while rehabbing his initial ailment, manager Aaron Boone told reporters Wednesday, according to James Wagner of The New York Times.
Boone didn't disclose the exact nature of Stanton's shoulder problem but said the 29-year-old was feeling "residual stuff" in the area. As a result, Stanton received a cortisone shot in his shoulder and will now rest for a few days. The good news, however, is that his bicep strain is fully healed.
Stanton will remain in California to rehab his shoulder after the Yankees leave Anaheim. He's expected to rejoin the team in Arizona, according to ESPN's Coley Harvey.
The banged-up Yankees currently have 12 players, including Stanton, on the IL.
Clint Frazier nearly grew that number to 13 when he jammed his ankle into second base during Monday's 14-inning affair with the Angels. Although Frazier remained in the game, Boone said the outfielder underwent an MRI on his ankle Wednesday due to extra swelling, according to Newsday's Erik Boland.
Despite the slew of injuries, New York enters Wednesday's play sporting a 13-10 record.
