Houston Astros vs Seattle Mariners — Apr 12, 2026 | AI-prognos & statistik

Luis Castillo’s combination of command and late life on the four-seam/slider mix figures to neutralize the heart of Houston’s order for the first trip through the lineup. Expect a quick start for Castillo, with six strikeouts by the end of the fourth and only one hard-hit ball allowed. Seattle scratches out an early run in the second when Cole Young legs out a double and Cal Raleigh dumps a single into right. Lance McCullers Jr. opens with crisp velocity but loses the zone in the fifth; his curve begins to back up and the changeup leaks over the inner third. A two-run J.P. Crawford double off the wall pushes Seattle ahead 3-1 and forces Houston to the bullpen earlier than planned. Once the Astros turn it over to a thin middle-relief corps, the matchup tilts further: Bryan Abreu’s control woes gift Seattle an insurance run in the seventh, and Steven Okert surrenders a Luke Raley opposite-field RBI single in the eighth. Houston’s lineup does flash its trademark power. Yordan Alvarez drives a Castillo changeup into the right-center gap for an RBI in the fourth, and rookie Cam Smith ambushes a Matt Brash fastball for a solo shot in the sixth. But the rally potential is blunted by Castillo’s ground-ball profile and Seattle’s clean infield defense; Jeremy Peña’s two groundouts with men aboard kill budding threats. Andrés Muñoz slams the door with a 1-2-3 ninth, touching 101 mph and freezing Christian Walker on a back-door slider. Seattle’s superior starting pitching, fresher high-leverage arms, and Houston’s battered bullpen prove decisive. Mariners 5, Astros 3.
