Yankees shortstop Derek Jeter has been cleared to progress into baseball activities and running, the team announced on Thursday.

Jeter was examined on Thursday in Charlotte, N.C., by Dr. Robert Anderson, who performed the initial surgery after Jeter fractured his left ankle in last year's American League Championship Series.

Dr. Anderson determined that the injury is healing, the Yankees said.

Jeter, who turns 39 later this month, has been working out at the club's training complex in Tampa, Fla., with his activities including playing catch, hitting off a tee and fielding ground balls hit directly at him on the outfield grass.

The Yankees have offered only a vague timeline for Jeter's return, saying that they expect him to be playing in Major League games sometime after the All-Star break. Jeter had targeted being in the Opening Day lineup before suffering a new fracture in his left ankle during Spring Training.
