Ryan Zimmerman out 4-6 weeks with broken thumb

Washington Nationals' third baseman Ryan Zimmerman will be out for 4-6 weeks after fracturing his thumb in Saturday's game, according to a team announcement. ZImmerman jammed his hand while diving back to second base on a pickoff attempt.

The loss of Zimmerman, who is batting .364 with 2 HR and 6 RBI so far this season, will be a significant one for the Nats, who already lost starting catcher Wilson Ramos for 4-8 weeks due to hand surgery. The team has also lost Denard Span (concussion) and Doug Fister (strained lat) to injuries early in the season, causing them to play the first part of the season with limited depth.

According to Dan Kolko of MASNSports.com, the Nationals will likely use an infield of Adam Laroche, Danny Espinosa, Ian Desmond and Anthony Rendon until Zimmerman gets back. Washington is also expected to call up Zach Walters from Triple-A Syracuse to provide infield depth alongside Tyler Moore and Kevin Frandsen.
