The San Francisco Giants are set to face off against the Arizona Diamondbacks in a crucial matchup at Chase Field, aiming to even the four-game series. The Giants, after a dramatic extra-innings victory in Game 3, are looking to build momentum against a D-backs team that has struggled recently, going 2-5 over their last seven games. Starting pitcher Robbie Ray, boasting an impressive 2.75 ERA this season, will take the mound for the Giants, while Arizona counters with Brandon Pfaadt, who has a 5.38 ERA.

For bettors, the odds are tight, with the Giants slightly favored at -110 on the moneyline while the Diamondbacks sit at -109. With the total set at 8.0 runs, the Giants' historically strong performance with Ray pitching (13-4) suggests a potential lean towards the over. Key betting trends indicate that 6 of the last 8 matchups between these teams have gone over the total, adding further intrigue.
