The San Diego Padres host the San Francisco Giants at Petco Park on Friday, July 31, 2026, with first pitch set for 9:45 PM ET. Bradgley Rodriguez takes the hill for San Diego against lefty Carson Whisenhunt in what figures to be a compelling NL West divisional clash. With the Padres rolling out a loaded lineup topped by Fernando Tatis Jr., Manny Machado, and Jackson Merrill, expect San Diego to look for a strong showing at home against a familiar rival. The game airs on Apple TV and local radio on KWFN 97.3 FM.

Starting Pitchers: Rodriguez vs. Whisenhunt

Bradgley Rodriguez draws the start for the Padres. Statistical lines for Rodriguez are not available heading into this one, so the focus will be on watching how he commands the strike zone and manages a Giants lineup that is capable of working counts. On the other side, the Giants counter with Carson Whisenhunt, a left-hander whose numbers for the current season are also unavailable ahead of first pitch. What we can say is that a Padres lineup built around right-handed bats like Machado, Tatis Jr., and Ty France will be watching closely for how Whisenhunt attacks them early in the game.

• 1. Fernando Tatis Jr. — RF
• 2. Luis Rengifo — 2B

• 7. Xander Bogaerts — SS

Keys to Watch at Petco Park

Tatis Jr. Sets the Tone at the Top

Fernando Tatis Jr. leads off and gives the Padres an immediate offensive threat with plus speed and the power to punish a mistake on the first pitch of the game. How Whisenhunt chooses to handle Tatis Jr. in his first at-bat will set the tone for the entire night. If Tatis Jr. gets on base early, San Diego's offense has the depth in this lineup to do real damage.

Merrill and the Middle of the Order

Jackson Merrill hitting fifth keeps a consistent threat behind the heart of the order. With Machado third and France fourth, Whisenhunt cannot simply pitch around one bat. Merrill's ability to make contact and drive runners in from the five-hole gives the Padres a legitimate threat up and down the lineup.

Bogaerts and the Bottom Third

Xander Bogaerts hitting seventh alongside Freddy Fermin and Jase Bowen means San Diego's bottom third is not a place for opponents to breathe easy. Bogaerts brings experience and the ability to get on base, which can make the lineup feel continuous rather than top-heavy.

Rodriguez's Command on the Home Mound

For the Padres to win this one, Rodriguez needs to keep the Giants from stringing together crooked innings. Petco Park can quiet offense, but only if the pitcher holds up his end. Rodriguez's ability to limit walks and induce weak contact will be the central story on the pitching side.

Prediction

This is a winnable home game for San Diego. The lineup construction gives the Padres multiple avenues to score, and the home crowd at Petco Park adds a layer of energy that Whisenhunt will have to navigate. Rodriguez's performance is the key variable. Expect a competitive, low-scoring game that the Padres take by a run or two late.
