In this Seattle Mariners vs Houston Astros Prediction, the Mariners are coming as -140 road favorites. The Mariners are rightfully favored, as they have a better overall record, and have the same road record, as the Astros have at home. Astros have a better bullpen, but Kirby has been amazing against the Houston bats historically, and the Mariners have a superior batting average and are better against righties. I certainly trust Kirby more than I trust McCullers, so I will go with the Seattle Mariners on the moneyline in the first 5 innings of this game.
