Cashman said that he had seen the photographs in Friday's New York Post, in which the 37-year-old shortstop wore a protective boot while walking through South Beach in Miami and appeared to have put on some pounds. The Post's back-page headline was "Derek Eater."
"I saw that the picture said he's heavy," Cashman said. "I can't tell you he's heavy. Even if he was, I'm not worried about Derek Jeter in that capacity in any way, because you're not going to find anybody more committed to being the best that he can be than Derek Jeter."
Cashman said Jeter had a recent checkup in North Carolina and that the Yankees were told his recovery from the Oct. 20 procedure is going well and at no time was Jeter's weight mentioned.
The 38-year-old Jeter fractured his ankle in Game 1 of the American League Championship Series against the Tigers, and he has been instructed to do nothing but rest at this time.
At the time of the operation, the Yankees were told it would take four to five months for Jeter to completely heal. He is expected to begin workouts in January.
"He's going to be ready for us by Opening Day," Cashman said. "He'll be a restricted player early in camp, but all indications are very strong for a full and healthy recovery. He just has to wait it out, that's all."
