Team Analysis
Arizona Diamondbacks
The Diamondbacks have split their last 10 games at 6-4, showing flashes of offensive efficiency but lacking sustained dominance. Their last five contests at 3-2 with 5.2 runs per game highlight a lineup that can score but doesn’t always generate momentum. Geraldo Perdomo has been one of the steadier contributors, yet the team’s 34-39 road record underlines how inconsistent they’ve been away from home.
Corbin Carroll’s power has provided some spark, but the Diamondbacks have struggled to stack wins when traveling, leaving them vulnerable against higher-scoring home teams. Ketel Marte adds balance, though the offense tends to flatten when facing stronger pitching environments. The data points to a capable but uneven unit, and that instability makes them the weaker betting side in this spot.

Away Record: 34-39 • Home Record: 38-34
Last 5 Games: 3-2 (5.2 RPG)
Last 10 Games: 6-4 (4.9 RPG)
San Francisco Giants
The Giants have taken control offensively with 7-3 over their last 10 games while averaging 7.8 runs per contest, a pace that dwarfs most National League teams. Their 3-2 mark in the last five games still produced 6.8 runs per outing, underscoring how their bats remain potent even in tighter series. Rafael Devers has been the centerpiece, consistently driving in runs and setting the tone for the lineup.
Willy Adames adds another layer of power, while Heliot Ramos supplies depth that forces opposing pitchers to work through every at-bat. Their home record of 36-34 shows a balanced ability to capitalize in their own ballpark, and the scoring surge has made them one of the more reliable Over teams in recent weeks. With their current rhythm and lineup production, the Giants hold the clear betting edge.
