The Padres beat the Diamondbacks 6-4 on Saturday in Game 1 of MLB’s Mexico City Series, and Mason Miller finished it the way he has finished so many games this season: with no drama. Miller entered the bottom of the ninth with a two-run lead and retired Alek Thomas, Jorge Barrosa and Ketel Marte to lock down the win.
The save extended Miller’s scoreless streak to 34 2/3 consecutive innings, breaking the Padres’ franchise record of 33 2/3 set by Cla Meredith in 2006. He has struck out 27 hitters in 13 1/3 innings in 2026, allowing no runs, three hits and two walks while posting a 0.38 WHIP and leading the majors with 10 saves.
The finish capped a comeback after Arizona built a 4-0 lead. Germán Márquez gave up four runs and six hits over six innings, and the Diamondbacks struck in the second with singles by Ildemaro Vargas and Nolan Arenado, a two-run double by Jose Fernandez and a two-run homer by Alek Thomas. Arizona starter Zac Gallen was forced out before the fourth inning after taking a line drive off his pitching shoulder in the third and finishing the inning before Brandon Pfaadt took over.
San Diego answered with two solo homers from Ty France and then broke the game open in a four-run seventh. Gavin Sheets delivered a two-RBI single, and Freddy Fermin and Ramon Laureano added sacrifice flies as the Padres turned a deficit into a lead they would not give back. In the end, Miller’s ninth inning was the final proof of how far the game had shifted.
The result mattered because the Padres found a way to survive an early hole on a night when the Diamondbacks had control and because Miller’s run has become one of the defining numbers of San Diego’s season. The comeback in Mexico City left Arizona chasing after a lead that vanished in one inning and San Diego holding the first win of the series.
