PHOENIX — Pinch-hitter Raimel Tapia hit a grand slam in Colorado's six-run seventh inning, Nolan Arenado had a pair of two-run homers and the Rockies rallied to beat the Arizona Diamondbacks 11-10 on Friday night.

Arizona built an 8-5 lead through six innings behind Ketel Marte's career-high four RBIs and a big night by A.J. Pollock.

The Diamondbacks brought in Archie Bradley (2-2) in the seventh, an inning earlier than usual.

It didn't turn out well.

Carlos Gonzalez hit a run-scoring single, and Bradley, who entered with a 1.97 ERA, walked in another run. Tapia, who had two previous career home runs, hit his first grand slam just over the wall in right to put Colorado up 11-8.

Scott Oberg (5-0) got two outs in the sixth inning for the Rockies, who have won six straight. Adam Ottavino gave up a run in the ninth before striking out Jon Jay with a runner at third for his third save.

Pollock tied a team record with five hits and scored three runs. David Peralta had four hits for the Diamondbacks.

The Rockies have a knack for jumping on teams early, leading the majors with 80 first-inning runs and 29 homers. They tacked onto those totals on Arenado's two-run homer off Robbie Ray.

The Diamondbacks answered in the bottom half, though, going up 3-2 on Marte's two-run single and a passed ball by catcher Tony Wolters.

Arizona tacked on two more runs in the third, but German Marquez, baseball's hitting leader among pitchers, floated a run-scoring single to right in the fourth. He's 7 for 13 in his past five games, raising his average to .361.

Marquez allowed six runs — five earned — on eight hits and struck six in five innings.

Arenado tied it in the fifth, curling a two-run homer just over the wall and inside the foul pole in right for his 25th of the season.

Ray allowed five runs on eight hits in 5 1/3 innings.
