Recent offensive struggles plague both sides—Seattle hitting just .182 over its last 10 games while Boston has managed only three runs in four of its past five—but the Red Sox benefit from home advantage, a stronger overall pitching staff, and the return of key contributors like Roman Anthony and Trevor Story. Probable starters George Kirby (9-10, 4.02 ERA) and Payton Tolle (8-6, 3.09 ERA) set up a matchup that tilts toward Boston, though late-season roster moves and bullpen availability could influence outcomes across the three-game set.
