Ryan Zimmerman left Tuesday night's game with a strained right hamstring and is scheduled to have an MRI on Wednesday morning.

He left in the sixth inning of the Washington Nationals' eventual win over the Colorado Rockies.

"It's pretty sore tonight. Get the MRI, get some results tomorrow and see where we're at," Matt Williams said. "It's concerning. Anytime you have to leave the game with a hamstring injury, it's concerning."

Zimmerman missed 44 games with a fractured right thumb earlier this season but has played well since coming off the disabled list June 3.
