Team Analysis

Cincinnati Reds

The Reds have gone 3-2 across their last five games, showing balanced scoring with 3.8 runs per outing. On the road, their 31-32 record demonstrates competitiveness that travels well, particularly when paired with a strong bullpen ERA of 3.79. Elly De La Cruz continues to anchor the lineup with impactful production, giving Cincinnati a reliable offensive spark in tight games.

Over their last 10 games, the Reds have averaged 5.6 runs while going 6-4, a trend that highlights their ability to sustain pressure against opposing staffs. Miguel Andujar has provided steady contact hitting, while Noelvi Marte adds depth that forces pitchers to navigate a dangerous middle order. With consistency across multiple bats and a pitching staff keeping opponents in check, Cincinnati enters this contest as the more trustworthy side.

  • Batting Average: 0.248
  • Total Runs Scored: 581
  • Home Runs: 127
  • OBP: 0.318
  • SLG: 0.392
  • OPS: 0.71
  • ERA: 3.79
  • WHIP: 1.23

Arizona Diamondbacks

Arizona has been inconsistent, going 2-3 across its last five games while averaging 4.4 runs. At home, their 32-31 record reflects mediocrity rather than dominance, leaving them vulnerable against sharper opponents. Geraldo Perdomo’s run production has been a bright spot, but uneven support around him has left games slipping late.

Across the last 10 contests, the Diamondbacks are just 5-5, producing 4.8 runs per game, a middle-of-the-pack output that fails to separate them from stronger competition. Ketel Marte’s power remains a threat, but with Corbin Carroll’s efficiency dipping, the lineup has lacked balance. Combined with a 4.55 ERA that too often puts them behind early, Arizona enters this matchup with less reliable form than their opponent.

  • Batting Average: 0.251
  • Total Runs Scored: 628
  • Home Runs: 178
  • OBP: 0.325
  • SLG: 0.439
  • OPS: 0.765
  • ERA: 4.55
  • WHIP: 1.33

Away Record: 30-35 • Home Record: 32-31
Last 5 Games: 2-3 (4.4 RPG)
Last 10 Games: 5-5 (4.8 RPG)

Arizona Diamondbacks’ last 10 games have averaged 9.3 combined runs, with 6 games clearing the same number of 9.

Moneyline Betting Prediction

Cincinnati Reds’ 6-4 surge over its last 10 games, paired with a winning head-to-head sweep of Arizona earlier this season, shows a clear performance gap. The Reds have proven more efficient offensively and steadier on the mound, while the Diamondbacks’ home record has failed to inspire confidence. With production spread across multiple bats and a stronger recent scoring profile, Cincinnati is the sharper side to back outright.

The Cincinnati Reds at +115 fit a live underdog profile on recent numbers.

Over/Under Prediction

Recent five-game scoring: the Arizona Diamondbacks are at 4.4 RPG and the Cincinnati Reds at 3.8 — a useful baseline against the total.

These teams are combining for 8.2 runs per game recently — below the posted total of 9.0. That points toward the Under 9.0.
