Ryan Zimmerman dealing with 'pretty substantial' strain

Nationals manager Matt Williams said Wednesday that the hamstring strain suffered by third baseman Ryan Zimmerman was "pretty substantial," masnsports.com reports.

Zimmerman is set to be re-evaluated after a couple weeks, and he'll almost assuredly be on the disabled list for longer than the 15-day minimum. He has hit .282/.345/.456 with five home runs and 36 RBI in 195 at-bats.
