Pablo Reyes' pinch-hit RBI single in the ninth inning Friday gave the Pittsburgh Pirates a 3-2 walk-off win over the visiting Cincinnati Reds.

With the Pirates trailing 2-1 in the ninth against Reds closer Raisel Iglesias (2-9), Colin Moran led off with a single, then left for pinch runner Erik Gonzalez. Jose Osuna singled, and Adam Frazier tied it at 2-2 with a bloop single to drive in Gonzalez.

Joe Musgrove replaced Osuna at second, and he and Frazier moved up on Jacob Stallings' sacrifice bunt. Reyes then lined a 1-1 slider to left to give the Pirates eight straight home wins against the Reds.

Rookie sensation Aristides Aquino was 3-for-4 with a homer and an RBI double for Cincinnati, which had its two-game win streak snapped.

Pittsburgh starter Mitch Keller, pitching in his sixth big-league game, pitched six-plus innings and struck out a career-high nine. He allowed one run and six hits, with one walk.

Felipe Vazquez (4-1) pitched a scoreless ninth.

Cincinnati starter Anthony DeSclafani gave up one run and five hits in six innings, with four strikeouts and two walks.

In the second, Aquino and Keller faced off, rookie against rookie, for the first time. On a 1-0 pitch, Aquino uncorked a shot to left for his 12th homer in his 22nd career game -- all coming this month -- for a 1-0 lead. As he has with earlier home run totals, Aquino set a record as the fastest major leaguer to reach 12 homers.

The Pirates tied it in the sixth. Bryan Reynolds drew a leadoff walk. Starling Marte followed with his 20th infield hit. They advanced to second and third on Josh Bell's flyout to center. Moran's groundout to first base was enough to get Reynolds home to make it 1-1.

In the eighth against reliever Keone Kela, Cincinnati's Freddy Galvis doubled to right with one out. After Eugenio Suarez struck out, Aquino doubled to the corner in left to drive in Galvis to make it 2-1.
