ARLINGTON -- Rangers right-hander Colby Lewis exited his start against the Reds on Tuesday after five innings after experiencing cramps in his right triceps. He will be re-evaluated on Wednesday.
Left-hander Cesar Ramos came on in relief to begin the sixth.
Lewis was not sharp in his five innings, allowing six runs on five hits. Just four batters into the game, Reds right fielder Jay Bruce took him deep for a three-run homer to left-center.
The 36-year-old right-hander exited in line for his first loss of the season after a 6-0 start.
