Michael Pineda 'sad' about setback

NEW YORK -- The wait for Michael Pineda to rejoin the New York Yankees starting rotation just got a little bit longer.

Pineda, who has not pitched since April 23, when he was ejected from a game against the Red Sox for using pine tar on the ball, will be shut down another 10 days, at least, after a recurrence of the shoulder muscle soreness that landed him on the disabled list on May 6 after he came off from suspension.

"That's a doctor's call," Joe Girardi said before Sunday afternoon's game against the Twins. "I think the last time we shut him down 10 days before he picked up a baseball, and I'm sure it will be 10 days here, maybe a little more depending on what they feel. It's not what we want. It's very similar to what he had about six weeks ago."

Pineda reported pain in the same area -- the muscle between the latissimus dorsi and the shoulder -- after throwing two innings in an extended-spring game in Tampa on Tuesday. He underwent another MRI which revealed a "slight strain," which the Yankees believe is unrelated to the extensive shoulder surgery he underwent in 2012 after tearing his labrum in spring training.

"I don't feel that bad," Pineda said. "Not as bad as last time. It's a little better."

Pineda said he felt the pain after throwing on Tuesday, and again after playing catch on Thursday. He was supposed to have pitched in an intrasquad game Sunday in Tampa but was flown to New York to be examined by team doctors instead.

"I feel sad," he said. "I don't have nothing to do. But I'm keeping my head up, continuing my work, and that's it."

Pineda was 2-2 with a 1.83 ERA when he was originally shut down.
