PHOENIX (AP) — David Peralta hit a grand slam in Arizona’s nine-run eighth inning, Mark Trumbo homered and drove in four runs, and the Arizona Diamondbacks routed the bumbling Colorado Rockies 14-4 on Saturday night.
Arizona led 5-4 heading into the eighth inning behind Trumbo’s a three-run homer off Jorge De La Rosa (11-8) and seven effective innings by Trevor Cahill (2-8).
The Rockies came apart in the bottom half of the inning with two errors, a passed ball and a wild pitch. Colorado also walked in a run and Peralta capped the eight-hit inning with his first career grand slam over the pool in right-center.
Alfredo Marte added a solo homer. Cliff Pennington had three of Arizona’s 15 hits and scored three runs.
Nolan Arenado homered and had three RBIs for Colorado, which has lost eight of nine.
Cahill had pitched well lately, but Saturday’s game got off to an ominous start.
Colorado scored a run in the first inning when Marte misplayed Arenado’s double in the left corner and Cahill dropped a throw from Trumbo at first to allow another run to come across.
Cahill was sharp after that, allowing three runs on four hits and struck out seven for his first win since April 23.
Trumbo came off the disabled on July 11 and played well over his past nine games, hitting .375 with seven RBIs. Three of those came in the third inning, when he launched a three-run homer off De La Rosa deep into the seats in left, his first in 89 plate appearances.
De La Rosa also gave a run-scoring double to David Peralta in the first inning. The left-hander allowed four runs on six hits in six innings.
The Rockies pulled within a run on Arenado’s homer in the eighth inning, but a throw home by Arenado on Trumbo’s chopper in the bottom half sailed high for an error, allowing two runs to score.
Arizona poured it on from there, compounding Colorado’s mistakes by matching a team record for most hits in an inning.
Rockies: RF Michael Cuddyer, out since fracturing his shoulder on June 5, went 1 for 3 with an RBI for rookie-level Grand Junction in his latest rehab game. He is 6 for 10 with three doubles and four RBIs in three rehab games.
Diamondbacks: SS Chris Owings tested his bruised shoulder with 30 swings in the batting cage and is hoping to progress to a simulated game.
Rockies: Franklin Morales, who will start the series final on Sunday, has held left-handers to a .232 average.
Diamondbacks: LHP Wade Miley had his worst start of the season his last time out, allowing 10 runs in 4 2-3 innings against Kansas City on Aug. 5.
