WASHINGTON -- Nationals right fielder Jayson Werth, who is on the disabled list because of a right hamstring strain, will begin a rehab assignment at Class A Potomac on Wednesday.
Werth took 30 minutes of soft-toss batting practice and ran the bases on Tuesday before the Nationals' game against the Orioles. Both sessions took place before the team took regular batting practice.
"He looked outstanding, very strong," said hitting coach Rick Eckstein, who threw the pitches to Werth. "He was working on his positioning. We just had the better part of a half-hour of hitting. He did great. He looked wonderful."
Later in the afternoon, Werth was able to shag fly balls in center field and then take another round of batting practice with his teammates. There wasn't a report of a setback.
The Nationals are hoping that Werth can be back on a Major League field playing games sometime next week.
"He was moving around pretty good out there," Johnson said. "We just told him to take it easy and his reply was, 'I don't know how to take it easy.' But we'll see."
