Reds starter Scott Feldman struck out each of his first five batters and nine of his first 10 to keep Cleveland quiet much of his night. The Indians picked up a run when Jason Kipnis hit a 2-2 Feldman pitch for a leadoff homer in the top of the sixth.
Feldman finished with one earned run, four hits, two walks and nine strikeouts over six innings. Tomlin was out after 6 1/3 innings, charged with five runs (four earned), nine hits, no walks and four strikeouts.
Cincinnati created some space with a three-run bottom of the seventh that included an RBI squeeze bunt by pinch-hitter Arismendy Alcantara against Tomlin and Zack Cozart's two-out, two-run single against Dan Otero for a four-run lead.
