The biggest strength for San Francisco is its ability to consistently put the ball in play. The Giants hold the advantage in batting average, hits, home runs, and slugging percentage over Arizona. If the offense continues to produce at those levels, San Francisco has an opportunity to stay competitive despite its road record.
Arizona Tries to Build on Its Latest Victory
The Diamondbacks come into Wednesday’s contest with a 42-42 overall record and a strong 25-17 home record. Arizona recently defeated San Francisco 5-4 after losing three straight games to Tampa Bay by scores of 5-1, 4-2, and 6-1. Before that skid, the Diamondbacks earned a 9-4 victory over St. Louis. They have gone 2-3 over their last five games.

San Francisco Giants vs Arizona Diamondbacks Picks and Prediction
San Francisco Giants vs Arizona Diamondbacks Pick
- Pick: Arizona Diamondbacks Moneyline
I’ll take Arizona in this matchup. The Diamondbacks have the better overall record, a strong 25-17 home record, and they picked up a 5-4 victory over San Francisco in the most recent meeting. While the Giants hold the edge in several offensive categories, Arizona has been better at limiting baserunners with a lower team WHIP and fewer walks allowed. Playing at home gives the Diamondbacks the slight advantage.
San Francisco Giants vs Arizona Diamondbacks Total Pick
- Take the over if the total is set at 8.5.
I would lean toward the over if the total is set at 8.5. Both scheduled starters enter with ERAs above 4.90, including a 6.15 ERA for Arizona’s starter. The Giants have also hit 89 home runs this season, while Arizona has scored 355 runs. The previous meeting finished with nine total runs, and I see enough offense in the provided numbers for this game to finish above 8.5.
Final Score Prediction: Arizona Diamondbacks 6 – San Francisco Giants 5
