PHOENIX -- — Spencer Steer hit a three-run homer in Cincinnati's five-run eighth inning, and the Reds avoided a sweep by topping the Arizona Diamondbacks 6-1 on Sunday.

Austin Hays had three hits for Cincinnati, and Noelvi Marte had two hits and scored two runs. Brady Singer struck out nine while pitching six innings of one-hit ball.

The Reds (68-63) improved to 3-3 on a nine-game trip. They also moved within 1 1/2 games of the New York Mets for the third NL wild card.

Arizona wasted a sharp performance by Zac Gallen, who struck out seven in six innings. The Diamondbacks finished with two hits.

Marte sparked the decisive sequence for the Reds with a leadoff single against Kyle Backhus (0-3). He advanced on Elly De La Cruz's flyout and scored on Hays' tiebreaking single off Juan Burgos.

Following a Gavin Lux single, Steer hit a 397-foot drive to left for his 16th homer. TJ Friedl tacked on a two-out RBI single that gave Cincy a 6-1 lead.

Graham Ashcraft (8-5) pitched a scoreless inning for the win.

Lourdes Gurriel Jr. hit a sacrifice fly in the first to account for Arizona's only run. Cincinnati tied it in the sixth when Marte tripled and scored on a throwing error on Diamondbacks shortstop Geraldo Perdomo.
