Justin Masterson gave up three hits in a complete-game effort Wednesday and Cleveland backed him up with a five-run fourth inning to down Cincinnati 8-1.
The Indians completed a three-game sweep by finally giving Masterson some help. He came into the game having received the least run support of any starter in the American League.
Masterson (4-6) struck out nine and did not walk a batter, and the only run he allowed was unearned. It was the fourth complete game in his five major league seasons.
Bronson Arroyo (3-5) gave up five runs on eight hits in four innings to suffer the setback. It was Cincinnati's seventh straight loss in Cleveland.
