CHICAGO -- Cubs outfielder Justin Ruggiano underwent an MRI on his left hamstring, which he injured Wednesday trying to chase down Aaron Hill's fly ball and fell on the visitors' bullpen mound during Chicago's 7-5 loss to Arizona.
There were two outs in the ninth, the D-backs had just tied the game at 5, and they had a runner at first when Hill lofted the ball to right. Ruggiano ran after it, and the ball dropped just fair for a two-run triple. Ruggiano slid into the bullpen mound, grabbing his left hamstring.
The Cubs outfielder had to be helped off the field by athletic trainer Ed Halbur and manager Rick Renteria. Ruggiano was taken to a local hospital for the MRI.
In the sixth, Ruggiano hit his first Cubs home run, a two-run shot, which helped Chicago open a 5-2 lead.
