DENVER -- Yankees shortstop Eduardo Nunez, who left Sunday's 5-4 loss to the A's in the fifth inning due to tightness in his left rib cage, was unavailable to play Tuesday's series opener against the Rockies but said he felt "so much better" after receiving treatment and resting.
However, manager Joe Girardi is not expecting Nunez to be ready to play on Wednesday.
"That might be a little bit early," Girardi said. "He'd have to go through a series of hoops to get out on the field. But the first thing is you've got to make sure he's pain free just doing simple things."
Namely, hitting a ball off a tee and swinging in soft-toss drills.
With 10 players on the disabled list, the Yankees certainly aren't looking to add Nunez to that group. Were Nunez to be placed on the 15-day DL, the move could be made retroactive to Monday, but that determination isn't imminent.
"You kind of go day by day and see," Girardi said. "And if you really feel it's going to be close to 15 days, then I think you make a move. We're on Day 2, so I think it's too early, but we'll see."
Nunez underwent an MRI exam that revealed no structural damage. He said the inflammation in his rib cage -- while diminished -- is still present.
In Nunez's absence, Jayson Nix, who moved from third base to shortstop when Nunez left Sunday's game, made his fifth start at shortstop on Tuesday.
