Nationals put slugger Zimmerman on 15-day DL

WASHINGTON (Reuters) - The Washington Nationals placed slugger Ryan Zimmerman on the 15-day disabled list with an abdominal strain Tuesday.

Zimmerman has been dealing with the ailment since spring training and aggravated it during a game Saturday, though he was not sure exactly when he tweaked it.

Zimmerman is hitting .357 with four RBIs in eight games this season. The third baseman hit .307 with 25 home runs in 2010.
