WASHINGTON -- The Nationals say outfielder Jayson Werth had surgery on his broken left wrist and will miss more than six weeks.
Werth will be sidelined for 12 weeks, MLB.com reported Monday, citing a baseball source.
Werth's operation was at the Mayo Clinic in Rochester, Minn., a day after he hurt himself trying to make a sliding catch against the Phillies.
Werth was injured while trying to catch a blooper off the bat of Placido Polanco in the sixth inning of the Philadelphia Phillies' 9-3 win on Sunday.
Werth's glove got caught underneath him and he bent his wrist backward trying to grab Polanco's sinking liner. Werth stayed on the ground briefly before throwing the ball back to the infield. He walked off holding his left wrist.
Werth missed the entire 2006 season after an injury to his left wrist which placed his career in jeopardy. He broke the wrist in spring training 2005 with the Dodgers and played 102 games that season before undergoing surgery to repair a torn ligament in the wrist.
He joined Philadelphia in 2007 and became an All-Star outfielder in his four seasons there before signing a $126 million, seven-year deal with the Nationals before the 2011 season.
Werth's injury is the latest in a string of injuries that have already hit the Nationals.
Michael Morse, slated to be the team's cleanup hitter, hasn't played because of an injured back muscle. Third baseman Ryan Zimmerman has been on the disabled list with a shoulder injury, and fill-in cleanup hitter Adam LaRoche has missed the past four games because of a sore right side muscle.
Zimmerman and LaRoche are hoping to return for Washington's next game, Tuesday night at Pittsburgh.
Zimmerman took batting practice on the field before Sunday's game and said he felt good. Now, instead of building toward a full lineup, Zimmerman's return will just plug the hole left by Werth's injury.
"We're a resilient team," Zimmerman said. "It's frustrating. Anytime anyone gets hurt it's tough, but it's part of the deal. It's a long season and we're going to have to go through adversity. This team has the talent and the capability to do that."
LaRoche was also looking forward to joining a near-full strength lineup until Werth's injury.
"Never a good time to lose anybody, especially a guy in the heart of your lineup," LaRoche said. "We were looking forward to this next series, this next week, being together again. Now we're obviously short another big bat and a big part of this team. So, time for everybody to step up and make up for it as much as we can."
