First Pitch: Thin on the infield

Eduardo Nunez's injury may result in Joe Girardi needing to think outside the box.

Nunez left Sunday's game with tightness in his left rib cage, and while X-rays were negative, the Yankees could be in a tight spot with their roster if Nunez has to miss time. Nunez said he hopes to be back Tuesday, but Girardi wasn't so sure.

If Nunez can't play, and the Yankees don't call up anyone or make a trade, they would have just two players for the left side of their infield: Jayson Nix and recent acquisition Chris Nelson. The Yankees could call up a player from the minors, but Girardi made it seem like the Yankees will try to make due with what they have until Nunez is ready to return.

If either Nelson or Nix got hurt, of if the Yankees wanted to pinch-hit for either one (both are not hitting well), things could get dicey. Girardi may have to maneuver some players around to positions they don't normally play and hope for the best.

"I think for a couple days we're OK," Girardi said. "Sometimes you have to be a little creative."

UP NOW: The Yankees fell to the A's, 5-4, on Sunday. Andy Pettitte struggled, and Vernon Wells struck out to end the game.

ON DECK: The Yankees have an off day before they head to Colorado and begin a stretch of 17 games in 16 days. Andrew Marchand will have you covered on the blog.

QUESTION OF THE DAY: Are you concerned about the infield depth?
