Team Analysis
San Francisco Giants
The Giants enter with a 1-4 mark over their last five, producing 3.6 runs per game in that stretch, which highlights recent inconsistency. However, their ten-game pace of 4.7 runs indicates the offense still has the ability to rebound quickly, especially with Rafael Devers anchoring middle-order production. On the road, their 37-38 record reflects competitiveness away from home, giving them a path to value in this matchup despite the recent slump.
Willy Adames provides power depth that balances the lineup, while Heliot Ramos has shown timely hitting that can extend innings. Even with uneven recent scoring, San Francisco Giants’ offensive metrics across the season suggest a team capable of breaking through against Arizona Diamondbacks’ higher ERA staff. That combination of proven run creation and a balanced road profile makes the Giants more dangerous than their latest five-game record suggests.

Arizona Diamondbacks
Arizona Diamondbacks’ 4-1 record across the last five with 6.4 runs per game highlights a lineup in rhythm, with Corbin Carroll driving consistent power. Their 39-34 home record reinforces their comfort at Chase Field, where they’ve been able to push run totals higher. Geraldo Perdomo’s production adds an extra layer of offensive consistency that has helped sustain scoring momentum.
Over the last ten games, the Diamondbacks are 6-4 while averaging 5.9 runs, showing they are maintaining steady output. Ketel Marte’s contributions keep the middle of the order balanced, and the overall offensive pace has been strong. However, with a team ERA north of 4.40, their pitching staff has left openings for opponents, a vulnerability San Francisco is positioned to exploit.
- Batting Average: 0.251
- Total Runs Scored: 751
- Home Runs: 204
- OBP: 0.324
- SLG: 0.435
