TAMPA, Fla. -- There is no timetable for Derek Jeter's return from a strained right calf, but the Yankees captain is making progress in his rehabilitation program.

Working out early on Wednesday to avoid expected inclement weather, the 37-year-old shortstop showed some power, hitting two balls over the outfield fence in a span of four pitches -- one landed behind the left-field wall and the other toward right-center.

Jeter, who said he "feels good," saw four sessions of batting practice at New York's Minor League complex and took 43 swings. He took the first seven pitches he faced the opposite way to right field.

Jeter was placed on the 15-day disabled list on June 14 for the first time since 2003. He is six hits away from reaching 3,000 for his career.

"You're always anxious [to return]," Jeter said. "Well, you're anxious to play. I haven't played in a while, and I don't like missing games, so I'm looking forward to getting back onto the field."

Along with some power, Jeter showed progress in his baserunning. He picked up his speed from past days on sprints around the diamond. He ran seven from home plate to first, one from first to second base and two from first to third base.

Jeter also took routine ground balls on the grass, others at his normal infield position and made throws to first base before hitting off a tee and swinging at soft underhand tosses in the batting cage.

Although he said he has not discussed a return date with Yankees officials, Jeter plans to go through the same workout on Thursday.

"[I expect to] do the same thing [Thursday]," he said. "You just keep continuing to pick up the intensity, and we'll see what happens from there."
