Yankees starter Michael Pineda, who is on the disabled list with an injured throwing shoulder, felt discomfort in his lat muscle while playing catch on Friday and will be shut down, manager Joe Girardi announced after Saturday's win over the Twins, according to Danny Knobler of ESPNNewYork.com.
The 25-year-old hasn't pitched since April 23 in Boston, when he was ejected for having pine tar on his neck. He is 2-2 with a 1.83 ERA in four starts this season.
Girardi said he will be shut down "for a little bit."
The Yankees had hoped to have Pineda back sometime in June, Knobler reports.
"This was not the news we wanted," Girardi said. "But it's what we're dealing with. He's going to be shut down for a while."
Pineada was an All-Star in his rookie season with Seattle after going 9-10 with a 3.74 ERA in 28 starts. Injuries forced him to miss the next two seasons. SI WIRE: Nationals third baseman Ryan Zimmerman to play left field in rehab start
