Arizona Diamondbacks vs Houston Astros

September 4, 2026 ยท 8:10 PM ET ยท Daikin Park
ARI 74-67  ยท  HOU 72-69

๐Ÿ“Matchup Preview

Although the betting market favors the Houston Astros tonight (-131), the Arizona Diamondbacks may offer value behind Merrill Kelly, who has posted a 5.08 ERA this season.

Cristian Javier takes the mound for the favored Houston Astros, and has struggled this season.

The Arizona Diamondbacks have also won their last game. The Houston Astros have also won 8 of the last 9 meetings between these two teams.

Vegas still favors the Houston Astros at -131, but the underlying numbers point to a closer game than the line suggests.

SportsFBI's outlook favors the Houston Astros tonight, driven primarily by Houston Astros' recent form and Cristian Javier's pitching advantage. The Houston Astros enter as the stronger overall matchup.
