Final Mariners vs. White Sox Prediction
Seattle has a significant edge both on the mound and at the plate. While Davis Martin has shown flashes of consistency, this Mariners lineup—with Cal Raleigh and Jorge Polanco swinging hot bats—should apply pressure early. The White Sox have a tendency to fade late in games, and Seattle’s bullpen has been more reliable.
We expect Luis Castillo to pitch deep and steady the game, giving the Mariners a comfortable margin. Expect a few fireworks late from the M’s, and for the total to edge over the 8-run line.
🔮 Prediction: Mariners 6, White Sox 5
🎯 Best Bets: Mariners ML -206 | Over 8 Runs (-116) | Cal Raleigh 1+ Hit
