BALTIMORE -- In the midst of what was shaping up to be a dominant performance, Red Sox lefty Eduardo Rodriguez left Tuesday's start against the Orioles with tightness in his left hamstring in the fifth inning.
Rodriguez held the Orioles hitless through the first four innings, striking out seven while allowing just two walks.
Shortstop Xander Bogaerts ran swiftly to the mound to check on Rodriguez after ball two to Steve Pearce. Manager John Farrell and trainer Brad Pearson then came out, and Rodriguez walked off the mound.
Rodriguez spent the first two months of the season on the disabled list due to a right knee injury he suffered early in Spring Training.
