Rodriguez (0-2) yielded five runs (four earned) on two hits and three walks over 1.1 innings Friday, striking out one batter and taking a loss against the Guardians.
Rodriguez began his outing with a scoreless inning before Cleveland racked up seven runs in the second frame. It was his first appearance since April 29 due to a back injury. His season ERA jumped from 4.11 to 5.94 through 16.2 innings. The 27-year-old righty is lined up to make his next appearance in Boston next week, but his spot in the rotation seems far from secure. Rodriguez has yet to complete more than four innings in a start this season.
