Padres vs Diamondbacks Prediction 27 September 2026
📡 The opening two games of the series turned into an offensive shootout: Arizona cruised to an 11-4 win, while San Diego answered back with a 10-7 victory. The Diamondbacks saw their six-game winning streak snapped, but their bats stayed hot-18 runs scored over two days. For the series finale, the visitors will turn to Michael Soroka, who brings a 3.31 ERA to the mound, while the Padres had yet to announce their starting pitcher at the time of writing. Despite Saturday’s loss, Arizona can still count on a more settled starting rotation as they look to close out the series.
Arizona and San Diego have split the last ten evenly after two high-scoring games in the series.
📊 Over their last 10 meetings, the teams are dead even at 5 wins apiece. The current series is also tied 1-1: Arizona opened with an 11-4 victory, then San Diego responded with a 10-7 win. In five of those last 10 head-to-head clashes, the winning side has put up at least eight runs, so high-scoring innings and momentum swings are a common theme in this matchup. There’s no clear home-field advantage here, making the starting pitcher a crucial factor heading into Game 3.

⚾ Starting Pitchers
As of the latest update, San Diego have yet to officially announce their starting pitcher. With Walker Buehler limited to just 3.2 innings on Saturday, the bullpen had to shoulder a heavy workload in what turned out to be a high-scoring contest. That uncertainty surrounding Sunday’s starter becomes especially significant given Arizona’s explosive offense, which has racked up 18 runs over the past two games.
Michael Soroka gets the nod for Arizona, carrying a 9-5 record, a 3.31 ERA, and 110 strikeouts into this matchup. He offers a much more reliable option compared to San Diego’s brief outing on Saturday. In his most recent start on September 22, Soroka went seven strong innings to help the team secure a 7-2 victory. For the Diamondbacks, his ability to eat up innings is crucial after surrendering 10 runs in the previous game.
⭐ Editorial Prediction
San Diego have been formidable at home and just put up a ten-run response, so this pick certainly carries some risk. However, even in defeat, Arizona’s bats kept producing, pushing their tally to 18 runs across the first two games of the series. The last 10 head-to-head meetings are split 5-5, meaning there’s no clear systemic edge for the Padres in this matchup. The key variable in Game 3 is Soroka, who brings a 3.31 ERA for the visitors, while the Padres’ starter remains unconfirmed. If the right-hander can give Arizona some length early, the Diamondbacks’ current offensive form should provide enough support to answer Saturday’s 7-10 result. Our editorial pick: Arizona Diamondbacks to win.
