Matt McClain's two-out, two-run home run off Diamondbacks right-hander Zac Gallen broke a 2-2 tie in the bottom of the seventh. It sent Arizona to a third straight loss.

The Reds won the series opener, which was completed Saturday after it was suspended Friday night due to rain. Cincinnati took the game in 10 innings, 4-3, and then took Saturday's originally-scheduled 4:10 p.m. matchup in a 13-1 rout.
