Nationals right-fielder Jayson Werth, who is on the disabled list because of a right hamstring strain, took 30 minutes of soft-toss batting practice before running the bases on Tuesday. 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 took 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 the Major League field and playing games sometime next week. There is a possibility that he could start a rehab assignment this week. "When we feel it's safe for him to go out to rehab, we'll send him out to rehab," general manager Mike Rizzo said. "He thinks he is close, the trainers think he is close to going out and playing."
