The Arizona Diamondbacks open a three-game series against the Cincinnati Reds on Friday night at Great American Ball Park. Both clubs enter the weekend looking to gain ground in their respective division races, but both teams come into this game having suffered four defeats in their last five games. The pitching matchup features veteran left-hander Eduardo Rodriguez against Reds southpaw Nick Lodolo, and you will find my Diamondbacks vs Reds prediction below.
Our Diamondbacks vs Reds Prediction
- Pick: Arizona Diamondbacks Moneyline
- Confidence: 4 out of 5
Arizona Diamondbacks vs Cincinnati Reds Model Projection
- Score Projection: Arizona Diamondbacks 6 – Cincinnati Reds 4
- Win Probability: Arizona Diamondbacks 61%, Cincinnati Reds 39%
Arizona enters Friday with the stronger overall resume. The Diamondbacks own a winning record, have allowed fewer runs than Cincinnati, and hold a significant edge in starting pitching based on current performance. Rodriguez has been one of Arizona’s most reliable arms, carrying a 5-2 record and a 2.52 ERA into this start. Cincinnati counters with Lodolo, who has posted a 5.51 ERA and has struggled to work deep into games.
While Great American Ball Park can quickly turn games into high-scoring affairs, Arizona’s combination of superior pitching and a lineup led by Corbin Carroll gives the visitors the advantage. Carroll continues to be Arizona’s most dangerous offensive weapon, producing a .394 wOBA and 152 wRC+ this season. Cincinnati possesses power throughout the lineup, but inconsistent pitching and recent poor form make it difficult to trust the Reds against a quality starter.

- Arizona Diamondbacks Moneyline -114
- Over 9.5 Runs -103
- Corbin Carroll Over 0.5 Hits -311
Parlay Odds: +264
The foundation of this parlay is Arizona’s moneyline. Rodriguez has been considerably more effective than Lodolo this season, and the Diamondbacks have been the more complete team. Arizona has also performed well when listed as a favorite, winning more than 64% of those games.
The over is appealing because Great American Ball Park remains one of baseball’s most hitter-friendly venues. Cincinnati’s pitching staff ranks near the bottom of the league in ERA, and Arizona’s bullpen has been inconsistent throughout the season. Even if Rodriguez delivers a quality outing, there should be enough offense available once the game reaches the middle innings.
Carroll’s hit prop is the safest leg of the group. The Arizona star has been one of the National League’s most productive hitters, carrying a batting average of .280 with a .372 on-base percentage and extra-base power. Against a pitcher with Lodolo’s current ERA, Carroll is well-positioned to contribute offensively.
Arizona Diamondbacks vs Cincinnati Reds Home Run Prop
Corbin Carroll to Hit a Home Run +407
Carroll is Arizona’s premier power threat and enters this game with a .548 slugging percentage and a .394 wOBA. Lodolo has allowed hard contact throughout the season, and Great American Ball Park boosts home run production for hitters from both sides of the plate. At better than 4-to-1 odds, Carroll offers value as a home run prop selection.

Arizona owns the clear advantage on the mound entering Friday’s opener. Rodriguez has delivered front-of-the-rotation production all season, while Lodolo has struggled to prevent runs. The Reds possess enough power to remain dangerous at home, but their pitching staff has consistently placed them in difficult positions. With the Diamondbacks carrying the better starter, the stronger overall run prevention numbers, and one of the game’s hottest hitters in Carroll, Arizona is the preferred betting side in my eyes.
