The Astros sit on top of the American League West and are looking to close in on the pennant. Meanwhile, the red-hot Diamondbacks are suddenly battling for a playoff spot, and there will ne be no shortage of intensity in this matchup. Arizona has been underestimated before and will be looking to replicate their shocking 2023 run to the World Series.
Neither of these two sides was on a hot streak heading into the All-Star break, but there are still 70 games left to get into playoff form. Arizona has already turned things around, and there is no doubt about the intensity of this matchup, as this promises to be one of the best series of the season if both teams play up to their full capabilities. Will Houston’s dominant pitching be enough to tilt the series in their favor, or will the Diamondbacks be able to defend their home turf? Here are your expert MLB predictions to find out.
Series Introduction:
- Teams: Houston Astros at Arizona Diamondbacks
- Dates: Monday, Tuesday, and Wednesday, July 21st-23rd, 2025
- First Pitch Times: 9:40 PM EST on Monday and Tuesday, and 3:40 PM EST on Wednesday
- Venue: Chase Field in Phoenix, Arizona
Series Preview:
There is no shortage of tangible rewards for these two sides in this matchup. If Houston can extend their lead on top of the American League West, it will pull away from the Mariners and take control of their own playoff fate. However, if Arizona can win two, or even all three of these games, they will put themselves in a great position to sneak into the Wild Card race in the National League.
These two teams have not been built the same way, as Houston relies on their pitching for success while the Diamondbacks use their explosive hitting. Framber Valdez and Hunter Brown have been dominant for Houston, posting respective 2.75 and 2.43 ERAs this season, with a combined record of 19-8. The extra rest of the All-Star break will allow them both to suit up to give the Astros a serious advantage. Across the diamond, Arizona relies on Eugenio Suarez’s 35 home runs to generate offense, and has 40 more combined deep balls from Corbin Carroll and Ketel Marte.
Head-to-Head:
The Houston Astros are behind the Arizona Diamondbacks 69-80 in head-to-head wins all-time, but they have started to make up ground against their National League rivals. The Astros have won or tied their season series against the Diamondbacks in ten consecutive seasons. That includes a 5-1 record in the last two seasons. Houston has completely locked them down defensively, and a pair of star pitchers for the Astros has put them in a great position to do so again. The MLB odds favor the Diamondbacks to use their home field advantage, but the Astros could be a good pick at underdog baseball odds on your sportsbook.
Key Stats and Facts:
It will be a battle of pitching vs hitting. It is no secret that the Diamondbacks’ bats are capable of unlocking the puzzle that is Houston’s pitching. However, the more interesting matchup will be Arizona’s pitching against Houston’s batting. The Astros have struggled to score runs this season without the help of trash cans, but it is not as if the Diamondbacks have been shutting teams down from the mound. Houston has two players hitting .300 or better, Pena and Myers, but their batting order quickly falls off. If they can give their star pitchers the run support they need, Houston can certainly upset the baseball odds at your sportsbook.
Predicted Lineups:
The exact batting orders will not be released until shortly before the first pitch, but we have a pretty good idea of what these teams will roll with. There are no recent injuries, and both sides are well-rested after the All-Star break.
Houston Astros Predicted Batting Order and Lineup:
- 1: Isaac Parades
- 2: Cam Smith
- 3: Jose Altuve
- 4: Christian Walker
- 5: Victor Caratini
- 6: Yainer Diaz
- 7: Taylor Trammell
- 8: Mauricio Dubon
- 9: Brice Matthews
Arizona Diamondbacks Predicted Batting Order and Lineup:
- 1: Corbin Carroll
- 2: Ketel Marte
- 3: Geraldo Perdomo
- 4: Eugenio Suarez
- 5: Josh Naylor
- 6: Lourdes Gurriel
- 7: Adrian Del Castillo
- 8: Alek Thomas
- 9: Jose Herrera
Tips and Score Prediction:
The MLB odds favor Arizona to win this series, but I am confident they are incorrect. Houston has a pair of fantastic pitchers in Valdez and Brown that the MLB odds have not accounted for. Houston will be able to get at least one gem of a game from their hurlers, and that alone will allow them to pick up a crucial road victory. Arizona relies too heavily on the offensive production from their sluggers to be given MLB odds heavily in their favor against a division leader. You can take advantage of your sportsbook by grabbing Houston in the underdog role on the baseball odds.

Final Thoughts:
These two teams have both proven they can win in the postseason, but this could be a great time to take the Houston Astros in the underdog role. Arizona has been red hot with five straight wins, but the Astros are a much steeper task. Houston is one of the truly dominant teams, and they fully understand the importance of this section of the season for postseason seeding. The Astros will win this series, and for the right MLB odds on Sportzino, you can swing for the fences with an Astros 3-0 sweep.
