San Francisco Giants vs San Diego Padres — 4月 1, 2026 | AI予測と統計

Logan Webb gives San Francisco the superior starting edge against a still-rusty Germán Márquez. Webb’s heavy sinker should play in spacious Petco, and the Padres’ left-leaning middle order (Cronenworth, Bogaerts, Sheets) historically struggles with his changeup/slider mix. Márquez, meanwhile, has not been the same since elbow issues; his four-seamer has flattened and the Giants’ right-hand power—Chapman and Devers in particular—profiles well against him. Expect the Giants to pounce early: Arraez setting the table, Devers driving in the first-inning run, and Chapman lifting a third-inning fastball over the left-center wall. Márquez will settle briefly, but pitch count climbs and Lee’s speed manufactures a sixth-inning tally. The Padres’ offense rallies once Webb turns the lineup over a third time. In the fifth, Machado’s two-strike double and a sharp Tatis single even things, and Laureano’s seventh-inning opposite-field homer knots it at 3-3. Yet San Diego’s late-game leverage arms are inconsistent: the Giants take advantage in the ninth when Devers splits the right-center gap off Ron Marinaccio, plating the decisive run. San Francisco’s bullpen—Keaton Winn’s power sinker, Matt Gage’s slider, and Camilo Doval slamming the door—protects the slim lead. In a tight, low-scoring contest that mirrors the series opener, the Giants squeak out a 4-3 victory and leave Petco with a two-games-to-none series edge.
