Halfway through a 10-game suspension for using pine tar a second time and being even more obvious than the first time on April 10 at Yankee Stadium, the Yankees announced that Pineda has a sore lat muscle, which is near the ribcage.
Pineda felt pain after the first inning of a simulated game in Tampa at the team's minor league facility and removed himself. Before the game, the Yankees were awaiting MRI results but didn't seem to think he would start Monday in Anaheim.
"I would think that his start Monday is probably in jeopardy," said manager Joe Girardi, whose team fell to the Mariners 6-3 Tuesday. "But we'll wait for the results. He's having the MRI down in Tampa. He threw the first inning and felt a little stiffness, tightness, and he pulled himself."
Afterward, team spokesman Jason Zillo said that an MRI revealed a grade 1 strain of the teres major muscle, which is in between the lat and the shoulder and that Pineda will be re-evaluated at some point Wednesday.
If there was a positive development, it was that it was not Pineda's shoulder, which sidelined him for two seasons.
For now, right-hander David Phelps will stay in the rotation.
