Key players to watch in the Diamondbacks vs Rockies matchup
Corbin Carroll remains one of Arizona’s most important offensive players. He is batting .240 with a .331 on-base percentage and a .471 slugging percentage. Carroll has hit 22 home runs, driven in 73 runs and scored 90 times across 650 plate appearances. He has also stolen 21 bases in 24 attempts.
Geraldo Perdomo has provided a disciplined presence in the lineup. In 656 plate appearances, he is hitting .259 with a .365 on-base percentage and a .369 slugging percentage. Perdomo has nine home runs, 53 RBIs and 21 stolen bases, while his 13.7 percent walk rate highlights his ability to extend at-bats.
Jake McCarthy has delivered significant production and speed. He has 15 home runs, 83 RBIs and 77 runs scored. McCarthy is batting .295 with a .338 on-base percentage and a .486 slugging percentage. His 30 steals in 35 attempts make him a constant threat once he reaches base.

Injury report adds another layer of uncertainty
Both teams are dealing with several players on the injured list. Arizona’s absences include A.J. Puk, Cristian Mena, Ryan Thompson, Andrew Saalfrank and Tyler Locklear. Puk, Mena, Thompson and Saalfrank are listed on the 60-day injured list, while Locklear is also listed with a thumb injury.
Colorado’s injury list includes Willi Castro, Chase Dollander, Kris Bryant, McCade Brown, RJ Petit, Welinton Herrera and Pierson Ohl. Castro is listed on the 10-day injured list with a foot injury. The remaining players are listed on the 60-day injured list with elbow, back or shoulder issues.
These absences could affect bench depth, bullpen options and late-game substitutions. In a high-scoring ballpark, roster flexibility can become especially important if the game turns into a battle of relief pitching.
What could decide the game?
The opening innings may be crucial. Kelly and Adams will need to avoid free baserunners and limit hard contact, particularly with Coors Field capable of turning routine fly balls into dangerous extra-base hits.
Arizona’s recent momentum gives the Diamondbacks confidence, but Colorado’s home-field advantage should not be overlooked. Carroll and McCarthy could pressure the Rockies with speed, while Perdomo’s plate discipline may help Arizona create scoring opportunities throughout the lineup.
