With the Cubs out of position players, relievers Travis Wood and Spencer Patton (1-0) alternated between left field and the mound in the 14th inning, which ended with Patton getting the final out. Wood then finished it off with reliever Pedro Strop in left.
Bryant's only hit on Tuesday — a single off J.J. Hoover (1-2) — snapped the tie. Javier Baez added a grand slam in the 15th, the sixth career allowed by Hoover, which is a Reds record.
The National League's top team went 1-6 last week but has pulled out of the downturn by winning the first two games of a series against the Reds. The Cubs hit five homers — three by Kris Bryant — while taking the opener 11-8.
