Jeter unlikely to be activated Wednesday

NEW YORK -- Yankees shortstop Derek Jeter has yet to resume baseball activities and it appears unlikely that he will rejoin the team on Wednesday, the earliest possible date that he could be activated.

Jeter has not yet been cleared to swing a bat, take ground balls or run at the team's training complex in Tampa, Fla. The captain is on the 15-day disabled list with a Grade 1 strain of his right calf, which is still sore.

"We're getting to the point where Wednesday is probably in jeopardy," said Yankees manager Joe Girardi, adding, "but I can't rule it completely out."

Yankees general manager Brian Cashman has said that he does not expect Jeter to be back on Wednesday, when the team is scheduled to play the middle game of a three-game series with the Brewers.

Jeter, who turns 37 on Sunday, has been throwing for four days. That has generally been the most activity he has done, other than receiving treatment and indoor workouts.

"I can't give you a timetable," Jeter told The Associated Press on Friday in Tampa. "Best way to put it -- when I'm ready to play I'll be back."

Jeter is just six hits shy of becoming the 28th member -- and first in a Yankees uniform -- of the 3,000 hits club, but the club has insisted that the milestone will play no factor in how quickly it activates Jeter.

It is probable that the Yankees will have Jeter play in at least one Minor League rehabilitation game prior to taking him off the disabled list.

"You wouldn't expect it to be too long, but he's got to go through all the drills and got to be able to make sudden starts and have quick movements," Girardi said. "I don't really have an exact date or how long it would exactly take, but not too long."

Jeter tried to convince the club not to put him on the disabled list after the June 13 injury, stressing that he might be ready in 14 days or fewer, but putting him on the shelf has proved to be the prudent move.

In Jeter's absence, Eduardo Nunez has manned the starting shortstop duties while Brett Gardner and Nick Swisher have shared time in the leadoff spot. Girardi indicated in Cincinnati that Jeter would return to the leadoff spot upon his activation.
