The Yankees plan to allow Pineda to rest for a brief period before trying to get him back on the mound. Pineda made four starts for the team this season but has not pitched since April 23, the game against the Red Sox in which he was ejected for having pine tar on his neck.
"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," Yankees manager Joe Girardi said. "It's a doctor's call. It's not what we want. It's very similar to what he had about six weeks ago. It's unfortunate, but we'll try to get him going again."
With Pineda, CC Sabathia and Ivan Nova all on the disabled list, the Yankees are planning to push forward with a rotation comprised of Masahiro Tanaka, Chase Whitley, David Phelps, Hiroki Kuroda and Vidal Nuno.
