Seattle Mariners vs San Diego Padres — Mar 23, 2026 | AI-prognos & statistik

Joe Musgrove gets the ball for San Diego and should be able to lean on his heavy sinker/slider mix to keep the ball on the ground against a Seattle lineup that has struck out at an elevated clip on the road. Luis Castillo counters for the Mariners, but his four-seam has flattened a bit this spring and he’s been punished when he misses arm-side, particularly by right-handed power. Expect the Padres’ righty core of Fernando Tatis Jr. and Manny Machado to jump a first-time-through fastball, staking San Diego to an early 1-0 edge. The middle innings tip toward the home side. In the fourth, a leadoff walk to Juan Soto forces Castillo back into the stretch; Xander Bogaerts rifles a doubles-power gapper and Ha-Seong Kim plates both with a sharp single, building a 3-1 Padres lead. Seattle answers briefly in the third with a Julio Rodríguez opposite-field homer, but Musgrove strands traffic in both the fourth and fifth by spotting his cutter on the hands of Cal Raleigh and Ty France. Seattle’s best push comes in the sixth when Musgrove’s pitch count creeps north of 90. A flare by J.P. Crawford and a full-count walk to Rodríguez set the table; Eugenio Suárez greets reliever Robert Suárez with a two-run double off the left-center wall to tighten things to 4-3. The Padres’ bullpen stabilizes from there—Tom Cosgrove neutralizes Raleigh with a back-foot slider to end the frame. The late leverage swings back to San Diego. Seattle’s bullpen, already carrying the worst WHIP in the league, turns to Andrés Muñoz in the eighth, but he spikes back-to-back splitters and walks Soto. Machado rifles a heater into the Western Metal seats for a two-run cushion. Matt Brash minimizes further damage, but the Padres exit the inning up 6-4. Josh Hader takes the ninth and, despite a leadoff single by Jarred Kelenic, freezes Rodríguez with a backdoor slider and generates a 6-4-3 double play from France to seal it. San Diego’s slight edge in starting pitching depth and a healthier back end of the bullpen prove decisive, while the Mariners’ recent off-field dust-up does little to change the underlying matchup issues: run prevention remains their Achilles’ heel. Padres 6, Mariners 4—San Diego climbs back to .500, Seattle drops its third straight against NL West opponents.
