NEW YORK -- With 10 Yankees on the disabled list, manager Joe Girardi could believe in a good case of indigestion, starting with his own first and his shortstop's next. Indeed, on Sunday, Eduardo Nunez first thought his problem might have been something he ate.
"Started in the third inning," Nunez said. "I thought it might be some food, something like that.
"I kept playing. After I swing [in the third], it hurt a lot. I went out to play defense, I couldn't move."
Derek Jeter's replacement, who has already missed two two-game segments of his own this season after getting hit by pitches, had to leave Sunday's 5-4 loss to Oakland before the top of the fifth inning with tightness in his rib cage area. An MRI was negative and his status was termed day to day. Jayson Nix moved over from third to finish the game at short.
"[Nunez] just came to me in the fourth inning and said he had a little irritation," said Girardi. "He wanted to try to go, so I sent him to the on-deck circle and told him to take a couple swings.
"The last out was made, and I said, 'What did you feel?' He said it was irritated and I said, 'So you're done.'
"You don't want to make that a six-week injury if it can just be a couple days. We'll see how he feels Tuesday, although I don't think we'll have a player then."
