Rodriguez entered with two outs in the eighth. After finishing the inning, his spot came up in the batting order after Milwaukee had already scored three times.
Rodriguez hit a slow roller and then beat first baseman Garrett Jones to the bag for his first career hit in two at-bats.
Rodriguez warmed up for the ninth but left after talking to trainer Roger Caplinger. The Brewers said Rodriguez exited with a right leg cramp, but Rodriguez spent most of his time on the bases trying to stretch his left leg.
