Werth is expected to begin a rehab assignment with Class A Advanced Potomac in the next couple of days, though general manager Mike Rizzo said the 10-year veteran will largely be able to set his own schedule. Werth has been targeting a return to the Nationals around the first week in August.
"Jayson's a veteran player who's gone through a wrist injury before," Rizzo said. "So he's going to more or less set his own schedule and see when he's prepared to go out and go on a rehab assignment. My job will be to pull him back, because I know he wants to get out there sooner rather than later."
After hitting the ball well during Wednesday's lengthy batting practice session, Werth came back for another before Thursday's early 12:35 p.m. series finale with the Mets.
Rizzo said that Werth's wrist felt fine, though other parts of the outfielder's body were sore since he is still getting accustomed to swinging the bat again.
"He has full range of motion in the wrist and it's just the repetition of it," Rizzo said. "The beginning of the batting practice round was always more impressive than the tail end of it because of the fatigue of the wrist. So we need for him to build up stamina in the wrist and be able to take good, full swings and be at 100 percent strength when he gets out there and is ready to play in games."
