Derek Jeter came back to The Bronx yesterday, and if you didn’t know any better, you would think the Yankees shortstop was fine.

“He looked good to me,” said Jeter’s replacement, Jayson Nix, who was working at shortstop with the veteran before a 7-5 win over the Rays at the Stadium.

“It was the first time I’d seen him take ground balls since spring training,” Nix said. “He looked like he did before he got hurt. He definitely looked a lot better than in the spring.”

According to Nix, Jeter appeared to have more life in his legs.

“Just the spring in his step,” Nix said. “I don’t think that was there when I saw him the last time.”

Jeter was able to move to his left and his right in the field after he went through batting practice and reported no problems.

“I feel good,” Jeter said in front of his locker. “Everything’s been going as good as it can go.”

That is quite a change from earlier in the season, when the shortstop felt discomfort trying to rehab a fractured left ankle suffered during Game 1 of the AL Championship Series last season.

After his workload was cut, he visited North Carolina, where the surgery on his ankle had been performed, and doctors discovered a new fracture that Jeter believes happened before he was scratched from a spring training game in Clearwater, Fla., on March 19.

Still, Jeter — who will turn 39 on Wednesday — won’t really know how he’s doing until he starts running and sprinting. And he’s not sure when that will happen.
