Seattle is the side because the Mariners have the better recent form, better home record, and stronger staff numbers. Seattle has won four of the last five, while Kansas City has lost two straight and sits at 3-12 away from home. Hancock has a 0.98 WHIP with 32 strikeouts and only six walks, which gives Seattle a cleaner pitching setup than Kansas City’s full staff numbers. Lugo can keep Kansas City in the game, but the Royals’ 4.54 ERA and 1.43 WHIP leave less room for error after the starter exits. Seattle’s 10-7 home mark and 3.67 team ERA are enough to back the Mariners straight up.
