"Right now, he's progressing slowly," said Baker. "He's working hard in therapy to get strength and range of motion back."
For now, third base is in good hands with Todd Frazier, who has started at third in 13 of the past 15 games, and Miguel Cairo.
In 14 appearances since Rolen went on the DL, Frazier has batted .216 with three homers and seven RBIs. He hit a walk-off solo homer in Wednesday's 2-1 win over Atlanta.
"The guys that are playing third base have done a good job," Baker said. "But Scott Rolen is Scott Rolen. You miss his consistency, and lack of flare when he's not in there. He makes all the plays."
