"Derek Jeter's right knee is in better shape than Alex Rodriguez' left thumb.

While manager Joe Girardi said he doesn't know if Rodriguez will be available for the upcoming three-game series against the Red Sox that opens tonight in Boston, the manager was more positive about having the shortstop.

"He is day-to-day; we are hoping he will be able to play [tonight]," Girardi said of Jeter, who fouled a ball off his knee in the first game of Sunday's doubleheader and was scratched from the second tilt. "I could use him in an emergency [last night]."

After last night's 3-2 win over the O's, Jeter was optimistic he will play tonight."
