Houston Astros vs Arizona Diamondbacks Prediction

ATS PREDICTION

Arizona Diamondbacks Win

Predicted: 4-3

⚡71%

The Arizona Diamondbacks, with a solid 30-24 record, are in better form than the struggling Houston Astros (24-32) heading into this matchup. Diamondbacks' probable starter Eduardo Rodriguez has been excellent this season, posting a 2.31 ERA and 1.21 WHIP through 11 starts, including two recent scoreless outings. While Houston's Spencer Arrighetti has also had a strong 2026 with a 1.32 ERA through seven starts, his walk rate is a concern, and the Astros' offense has been inconsistent, scoring three runs or fewer in 15 of their 19 May games. Arizona's Ketel Marte is currently a hot hitter, which could be the difference in a tight game against Houston's struggling bullpen, which held the second-worst ERA in MLB as of late April.

SPREAD PREDICTION

Arizona Diamondbacks -1.5 (-1.5)

56%

Given Eduardo Rodriguez's ability to limit runs and the Diamondbacks' recent offensive surge, particularly from Ketel Marte, Arizona has a good chance to win by more than one run. The Astros' offensive woes and bullpen struggles make it harder for them to keep games close even with a strong pitching performance from Arrighetti.

TOTAL PREDICTION

Under 7.5

60%

With two impressive starting pitchers in Spencer Arrighetti (1.32 ERA) and Eduardo Rodriguez (2.31 ERA) likely on the mound, a low-scoring game is anticipated. Both pitchers have demonstrated the ability to work deep into games and suppress opposing offenses, suggesting that runs will be at a premium despite Houston's bullpen challenges.

⚠️ Moneyline: Arizona Diamondbacks

The Diamondbacks are playing at home, have a better record, and a hot offense. Eduardo Rodriguez is pitching exceptionally well, providing a solid foundation for a win. This represents an edge based on the implied probability of the odds versus our model's probability.

✅ Total Runs: Under 7.5

Both probable starters, Arrighetti and Rodriguez, have demonstrated excellent control and low ERAs this season, suggesting a pitcher's duel. While bullpens can be unpredictable, the starting pitching strength makes the under a good value bet.
