28 Jayson Werth, RF

The Nationals expected outfielder Jayson Werth to return from the disabled list Saturday, but he appeared to suffer a minor setback in his recovery from a hamstring injury Thursday.

Werth saw a doctor Thursday after feeling tightness in his strained right hamstring, and is in New York visiting with the team's specialist, according to The Washington Times.

"He wanted to go see another doctor in New York," manager Davey Johnson said Thursday. "Reason being, he felt a slight, little bit of tightness in his hamstring. He just wanted to check something out."

The team has yet to say officially, but it looks like Werth's return to the active roster could be delayed a few days. Werth has been out since May 2 due to this injury. 

Nationals outfielder Jayson Werth was supposed to continue his rehab assignment with the Potomac Nationals Thursday, but he's not with the team, according to James Wagner of the Washington Post. 

Werth said his hamstring feels fine, but he "needed more action." There's a 40 percent chance of rain near game time, and the Nationals might not like their highly paid outfielder playing a rehab game in poor weather. The Potomac Nationals are located just a half hour from Nationals Park, so Werth could be getting his work in with the major-league club Thursday. He is aiming to return to the Nationals Saturday.

Nationals right fielder Jayson Werth, who is on the 15-day disabled list with a hamstring strain, played three innings with Class A Potomac Wednesday, going 1 for 2 at the plate. He still hopes to return to the Nationals Saturday, the Washington Post reports.

"Pretty good," Werth told the Post after the game. "Been a couple weeks since I’ve been out there but a step in the right direction."

Werth is hoping to get three at-bats Thursday.

Nationals outfielder Jayson Werth (hamstring) is expected to begin a rehab assignment with Class A Potomac Wednesday. He's expected to come off the disabled list Saturday against the Padres.

Nationals outfielder Jason Werth, who is on the 15-day disabled list, could begin a rehab assignment with Class A Potomac either Tuesday or Wednesday, MLB.com reports. Werth, who is eligible to be activated off the 15-day disabled list Saturday, could be back in the lineup that same day against the Padres, barring any setbacks.
