Arizona Diamondbacks at San Diego Padres: Final Score & Recap

The Arizona Diamondbacks shut out the San Diego Padres 8-0 at Petco Park on July 6, 2026, handing San Diego a complete loss that saw the DiamondIQ model's estimate of a home win fall from 53 percent before first pitch to zero percent by the final out. Arizona did the bulk of its damage early, scoring two runs in the first inning and erupting for four more in the third to effectively decide the contest before the game reached its midpoint. The Padres committed two errors and managed eight hits but could not push a single run across against Arizona's pitching staff.

The most consequential swing of the night came in the top of the third inning, when Max Kepler connected on a home run off Walker Buehler that shifted win probability 14.2 percentage points in Arizona's favor according to the DiamondIQ model's estimate, the single largest play of the game. Lourdes Gurriel Jr. followed with a single off Buehler in the same frame, adding another 4.5 points of win probability, and Nolan Arenado's groundout in the first inning contributed a positive 4.3 points as Arizona manufactured its early lead. On the San Diego side, the Padres' most damaging moments were opportunities left on the table, as Sung-Mun Song's groundout in the second inning off Brandon Pfaadt carried a negative 7.5-point swing and Gavin Sheets' groundout in the first cost the home side another 6.0 points.

Brandon Pfaadt was the game's dominant individual performer, finishing with a WPA of plus-20.3 percent as he methodically kept San Diego's lineup off the board. Kepler led Arizona's offensive contributors with a WPA of plus-14.1 percent and a RE24 of plus-2.9, the strongest run-environment figure among position players. Gurriel Jr. added a WPA of plus-4.4 and Arenado contributed plus-4.1, rounding out the Diamondbacks' most impactful bats in what was a thoroughly one-sided affair from the third inning onward.
