What Should I Use My MLB Betting Bonuses on Tonight?
Seattle Mariners vs New York Yankees – Expert Picks
Seattle Mariners Moneyline (+110)
Seattle (56-63) enters Tuesday's series opener relying on starter Bryan Woo (8-8, 4.31 ERA, 127 K) to set the tone against New York (66-52).
Woo's high-velocity four-seamer plays well against a Yankees lineup that can struggle with elevated heat, giving Seattle a solid shot to limit early damage. Facing Yankees starter Ryan Weathers (5-7, 3.79 ERA, 132 K) and a New York bullpen coming off heavy weekend usage, taking the Mariners at +110 plus-money offers great value.
Over 8.0 Total Runs (-115)
Yankee Stadium’s short right-field porch regularly boosts scoring on warm August nights, and weather projections favor fly-ball carry toward right-center field.
Even though both Woo and Weathers boast solid strikeout totals (127 K and 132 K, respectively), high temperatures and middle-reliever fatigue favor late-inning offense. Expect power hitters on both sides to push this game past the 8.0 run line.
