Zimmerman had been out since April 10th with the injury after getting off to a hot start with a .357/.486/.536 line in 37 plate appearances. The blow is a significant one to a team that could use Zim's offense as they fight to stay over .500 the entire year; the Nats are currently at 12-13.. Now, the team will have to get by with a combination of Alex Cora, Jerry Hairston and Mike Morse at the hot corner.
Zimmerman's prognosis for a return is six weeks, although he will need to go on a rehab assignment that will lengthen his absence from the team. That puts his return at the earliest in mid- to late-June.For more baseball news, rumors and analysis, follow @cbssportsmlb on Twitter or subscribe to the RSS feed.
