Key Position-Player Matchups

Arizona Diamondbacks

1. Ketel Marte: Marte is enjoying another strong season with a .289 batting average and an OPS of .835. He’s been particularly effective against Márquez, hitting .375 in previous matchups. His ability to get on base and set the table for the heart of the lineup is crucial.

2. Corbin Carroll: A key power threat for the Diamondbacks, Carroll has launched 24 home runs with 78 RBIs. His .521 slugging percentage coupled with speed on the bases makes him a dual threat that could trouble Márquez.

Colorado Rockies

1. Kris Bryant: Bryant’s veteran presence remains pivotal for the Rockies. He’s hitting .265 with 20 home runs and a .810 OPS. Bryant’s success against Gallen (.300 average) could be a spark for Colorado’s offense.

2. C.J. Cron: With 22 home runs and 74 RBIs, Cron provides the Rockies with significant slugging power. His ability to capitalize on Gallen’s mistakes outside the zone could be game-changing.

The ballpark is known for its hitter-friendly environment, which could accentuate offensive performances. The weather forecast predicts a warm evening with temperatures around 85°F, which should further enhance the offensive conditions.

In terms of injuries, the Diamondbacks are monitoring the status of their shortstop Nick Ahmed, who remains day-to-day with a minor ankle sprain. Meanwhile, the Rockies will miss the services of Brendan Rodgers, who is sidelined due to a shoulder injury.

Advanced Metrics
