Milwaukee Brewers vs Seattle Mariners — 三月 18, 2026 | AI Prediction & Stats

George Kirby draws the start for Seattle and should neutralize Milwaukee’s right-hand heavy middle order with his elite command and newly polished splitter. Freddy Peralta counters for the Brewers, but his occasional early-inning shakiness on the road remains a concern, particularly against a Mariners lineup that slugged .465 at home last season. The Brewers strike first on a Sal Frelick leadoff double followed by a William Contreras RBI single, but Kirby settles in with four consecutive scoreless frames. Seattle answers in the second when Cal Raleigh ambushes a first-pitch fastball into the right-field seats. The decisive swing comes in the fourth: Julio Rodríguez works a full-count walk, J.P. Crawford rolls a seeing-eye single, and Ty France splits the right-center gap for a two-run double, flipping the score 3-1. Peralta’s pitch count climbs past 80 before the end of the inning, forcing an early trip to the bullpen. Milwaukee briefly levels the game at 3-3 in the fourth thanks to a Christian Yelich two-run shot off a hanging slider, and they edge ahead 4-3 in the sixth when Rhys Hoskins sneaks an RBI bloop off reliever Gabe Speier. Seattle’s pen tightens from there, with Andrés Muñoz lighting up radar guns in a perfect eighth. In the bottom of the seventh, Jarred Kelenic legs out an infield single, steals second, and scores on Crawford’s flare to left, knotting things at 4-4. The game stays deadlocked until the ninth, when Rodríguez ropes a 102-mph sinker from closer Devin Williams off the left-field wall for a walk-off RBI single. Key factors tilting the matchup Seattle’s way: • Kirby’s superior strike-throwing versus a Brewers lineup that ranked near the bottom third in contact rate. • A fresher, deeper Mariners bullpen after an off day, whereas Milwaukee used high-leverage arms in consecutive games. • Home-field advantage: Seattle went 50-31 at T-Mobile Park, and their speed plays well in the spacious alleys. Expect a tightly fought contest, but the Mariners’ balanced offense and late-inning relief edge deliver a 5-4 victory.
