"Still sore from surgery, Ryan Zimmerman began his rehab this morning by walking one mile on a treadmill. It took him 30 minutes to complete. "I was flying," he said.

After undergoing the operation on Tuesday and speaking with Bill Meyers, the specialist who performed the procedure, Zimmerman still thinks he will remain out for six weeks, which the doctor and the Nationals expected before surgery.

"There was a decent tear in there that he fixed," Zimmerman said. "But with what he looked at in the MRI, it was exactly what he thought it was going to be when he went in there. Most importantly, he thinks that the timetable that they set before he went in there is right, about the right time. So that's good to hear.""
