Their recent sweep of the Milwaukee Brewers was a statement series that showcased both their offensive depth and pitching prowess. However, Cincinnati will need to maintain this momentum as they face a challenging schedule ahead.

Arizona Diamondbacks

The Diamondbacks have split their last 10 games, going 5-5, but they are coming off a critical series win against the Los Angeles Dodgers. Despite this uneven stretch, they’ve shown flashes of brilliance, particularly with late-inning heroics. Arizona’s bullpen has been a highlight, often keeping them in close games. However, consistency remains a challenge as they navigate the competitive NL West landscape.

Head-to-Head History

This season, the Reds and Diamondbacks have squared off five times, with the Reds leading the series 3-2. Historically, Cincinnati has had the upper hand, winning 7 of the last 10 matchups between the two teams. This trend could play a psychological advantage in favor of the Reds as they prepare for this crucial encounter.

Pitching Matchups

Cincinnati Reds: Lucas Sims

Lucas Sims is expected to take the mound for the Reds. This season, Sims has posted a 3.78 ERA with a WHIP of 1.19. His strikeouts per nine innings (K/9) stand at an impressive 10.5, highlighting his ability to overpower hitters. In his last outing, Sims pitched seven strong innings against the San Francisco Giants, allowing just two runs while striking out nine. No significant injury concerns have been reported for Sims, making him a reliable arm for Cincinnati.

Arizona Diamondbacks: Zac Gallen

For the Diamondbacks, Zac Gallen will be the starter. Gallen has been outstanding this year, boasting a 2.95 ERA and a WHIP of 1.07, with a K/9 of 9.8. His last start was a seven-inning gem against the San Diego Padres, where he gave up only one run and fanned seven batters. Gallen is the ace that Arizona relies on to quell potent lineups, and he will be pivotal against Cincinnati’s dangerous bats.

Prediction and Confidence Level
