TAMPA, Fla. - Yankees shortstop Derek Jeter doesn't know when he will be able to return from a strained right calf.

"I can't give you a timetable," Jeter said Friday after throwing for the fourth straight day at New York's spring complex. "Best way to put it, when I'm ready to play I'll be back." The team captain, on the disabled list since June 14, is still awaiting clearance from the Yankees' medical staff to resume running, hitting and fielding grounders.

He's six hits shy of 3,000, a chase that's been on hold since getting hurt June 13.

Also, right-hander Bartolo Colon, sidelined by a strained right hamstring, threw 31 pitches in his first bullpen session. He also ran sprints in the outfield for the second consecutive day.

Converted reliever Mark Prior, on the DL at Triple-A Scranton/Wilkes-Barre due to a strained groin, played catch and is scheduled to have a mound session Saturday.
