After Ryan Zimmerman took full batting practice on the field today for the first time since he went on the disabled list last weekend with a hamstring strain, he mapped his schedule for rejoining the Nationals.

As Manager Davey Johnson said yesterday, Zimmerman expects to fly to Pittsburgh on Friday, the first day he’s eligible to play, and return to the Nationals lineup. He will play two rehab games at Class A Potomac on Tuesday and Wednesday, not Monday as Johnson had suggested. He plans to take two at-bats Tuesday and three on Wednesday while playing third base.

“Unless happens between now and Thursday,” Zimmerman said, he will be playing again Friday. Zimmerman no longer feels any pain in his hamstring. Today, he sprinted around the bases and took a full complement of batting practice. The recovery has gone as he hoped.

“It wasn’t anything bad,” Zimmerman said. “Usually, you can tell the difference between something bad and something not that bad. It’s definitely a relief. We’re not there yet, but we’re well on our way. Hamstrings, you never know.”

The time on the shelf has not inhibited Zimmerman’s throwing program as he returns from offseason surgery. He missed throwing for two days, but “that doesn’t make a difference,” Zimmerman said.

Since Zimmerman last played, the Nationals have gone 4-5. Top prospect Anthony Rendon, who has been the primary replacement for Zimmerman, is 3 for 18 with a double and a walk since his call-up from Class AA Harrisburg.
