The Arizona Diamondbacks unleashed a relentless offensive barrage Thursday night, crushing the Colorado Rockies 8-2 in a game that was effectively decided by the fourth inning. Geraldo Perdomo set the tone early, going 2-for-4 with three runs scored and two RBIs, while Lourdes Gurriel Jr. delivered the knockout blow—a three-run homer that capped Arizona's seven-run explosion against Rockies starter Bradley Blalock. The Diamondbacks' patience at the plate paid off, drawing four walks in the decisive fourth inning alone as Colorado's pitching unraveled. Eduardo Rodriguez silenced any hopes of a Rockies comeback, striking out six over seven dominant innings while allowing just one run on six hits.

Colorado's lone bright spots came from Kyle Farmer (3-for-4 with a solo homer) and Brenton Doyle (2-for-4 with a solo shot), but their efforts were drowned out by Arizona's balanced attack—six different Diamondbacks recorded RBIs. The loss drops the Rockies further into the NL West cellar, while Arizona's convincing win keeps their postseason aspirations alive as they continue to climb in a tight wild-card race.
