Player Prop #3: Cal Raleigh / Over 0.5 RBIs / +105 / 59% / Middle-of-order production and recent multi-run support games boost RBI chances; favorable matchup spot against Astros arms.

Public and money are aligned on the Mariners with no strong reverse line movement signals. Recent game logs show the Mariners generating more consistent run support while the Astros have mixed results. Offensive trends from both sides favor a slightly elevated total rather than a pitchers’ duel. The mathematical edge sits with Seattle on the moneyline and run line, with the Over offering secondary value.
