CLEVELAND -- Travis Hafner's Minor League rehabilitation stint expires Saturday, and the Indians are going to use every last minute of it.

Hafner, working his way back from right shoulder weakness and soreness, was not activated from the 60-day disabled list Tuesday, when the Indians made their September callups. Instead, he worked out with the Indians before their game against the White Sox, gearing up to play Friday and Saturday at a local Minor League site that is yet to be determined.

Pronk will either join short-season Mahoning Valley, Class A Lake County or Double-A Akron. Mahoning Valley's regular season wraps up Saturday, while Lake County and Akron are both in the playoffs.

Hafner played seven games with Triple-A Buffalo, batting .318 (7-for-22) with three doubles and four RBIs. Because the shoulder is an ongoing concern, he had at least one day off between each game and he only had more than three at-bats in one game.

"Right now, I can do three at-bats," Hafner said. "We'll keep going and build up the volume and get to where I can build off that."

The Indians will evaluate Hafner on Sunday to determine how much he'll be ready to play with the club. The club hopes to get him regular at-bats before season's end so that it can go into the offseason feeling good about his progress from an injury that has kept him on the DL since May 30.

Hafner said he has not discussed with the Indians whether he might have to play winter ball to get some offseason at-bats.

"Hopefully, I'll get back and play in some games," he said, "then we'll evaluate it from there."
