MINNEAPOLIS, Minn. -- The Red Sox placed Dustin Pedroia on the 10-day disabled list with left knee inflammation June 2. And he still is not participating in any baseball activities on the field.

"We're waiting for the swelling and the pain to go away, and then we go from there," manager Alex Cora said here today at Target Field.

Cora described Pedroia's progress as "up and down."

Pedroia visited with Dr. Riley Williams III in New York, N.Y. on June 5. Dr. Williams, who performed Pedroia's left knee cartilage restoration procedure Oct. 25, determined it was not related to the actual surgery.

Cora was asked if it's troubling to him Pedroia still hasn't begun baseball activities after resting for more than two weeks.

"Yeah, and him, too," Cora said about Pedroia. "But like I said before, it was major surgery. We didn't know what to expect. So we are where we are now. We're hoping that yeah, he'll be back. When? We don't know. But I still believe he's going to contribute this season and he's going to help us to win."
