Yankees (3-1) remain potent offensively but face pitching woes without Gerrit Cole (Tommy John recovery, 15-day IL) and Carlos Rodón (elbow, 15-day IL), plus Anthony Volpe sidelined (10-day IL); Mariners (3-2) counter with a deep rotation anchored by Luis Castillo's strong start, though J.P. Crawford nurses shoulder soreness. Pitcher-friendly park dimensions, home-ice edge for Seattle, and Yankees' West Coast travel could amplify bullpen decisions and late-inning volatility in game two.",
