Left fielder Jarrett Parker has left Saturday’s game against the Rockies with what appears to be a serious shoulder injury.

The Rockies had three runs in and led 4-0 in the fourth against Matt Moore when Parker outraced a DJ LeMahieu drive and caught it two steps from the wall. After he stopped himself by crashing into the wall he immediately grabbed his right shoulder.

Parker tried to trot off the field and went to his knees in the outfield as head athletic trainer Dave Groeschner ran to see him.

Aaron Hill replaced Parker in left field for the top of the fifth inning.
