"Third baseman Ryan Zimmerman jogged for the first time in his rehab from abdominal surgery, which remains in the "very early stages," Zimmerman said. The Nationals expect Zimmerman, who underwent the surgery 10 days ago, to return about four and a half weeks from now.

Before today, Zimmerman had only walked, "and that he was it," he said. He feels some swelling and soreness, which is to be expected, but less so than in the days immediately following the surgery. He has always deals with scar tissue from the surgery. Still, the mental aspect has been more challenging than the physical recovery.

"That's the hardest part, being patient," Zimmerman said. "Just sitting around, watching them play, not being able to do anything, is hard to do."

Zimmerman, who is rehabbing in Washington, watched every game of the Nationals' nine-game road trip, a weird sensation. He text messaged teammates during and after games, talking about certain situations. The Nationals have gone 15-14 without Zimmerman this year."
