Recent series results underscore Arizona’s momentum, including a walk-off three-run homer by Ketel Marte that sealed a 5-3 victory and set up a potential sweep. The Giants, mired at 20-29 and 10 games below .500, face roster challenges with Logan Webb on the injured list while relying on limited offensive sparks. Pitching matchups feature Arizona’s Merrill Kelly against San Francisco’s Tyler Mahle, with bullpen execution and late-inning defense likely to prove decisive in the closely contested NL West standings race.

Recent series results underscore Arizona’s momentum, including a walk-off three-run homer by Ketel Marte that sealed a 5-3 victory and set up a potential sweep. The Giants, mired at 20-29 and 10 games below .500, face roster challenges with Logan Webb on the injured list while relying on limited offensive sparks.
