Mariners vs Pirates Preview: Deep Pens, Big Stars

George Kirby takes the mound for Seattle with a 3.5 ERA and serious strikeout power. He's ranked 56th in baseball and brings real heat every time he pitches. Pittsburgh counters with Mitch Keller, an All-Star who's struggled this season with a 6.99 ERA. Both pitchers know what's on the line here. The Mariners' rotation is one of baseball's deepest, anchored by Logan Gilbert and Luis Castillo. Keller needs to find his rhythm against a Seattle lineup that feeds off strong starting pitching. This matchup sets the tone for everything.

The Mariners roll into Pittsburgh with plenty of firepower but some question marks. Randy Arozarena, the speedy left fielder, could return Tuesday after hamstring issues sidelined him. Dominic Canzone hurt his hamstring Sunday but traveled with the team. Luke Raley deals with illness but's been making progress. The good news? Victor Robles stepped up when Arozarena went down. Seattle's bullpen features Andrés Muñoz, one of baseball's premier closers with 38 saves last year. These guys can lock down games late. The Mariners sit at 40-39 and need every game.

The Pirates are 39-39 and hungry at home, 20-19 in PNC Park. They just notched a win and have momentum. Paul Skenes is Pittsburgh's ace superstar, but Mitch Keller has to step up when his turn comes. Oneil Cruz, the dynamic center fielder, is out for weeks with hand fractures. The Pirates' bullpen needs work, but Dennis Santana closes and Gregory Soto handles important innings. Jared Jones dealt with a line drive to the elbow but seems okay. Pirates fans know their team can compete when the staff delivers.
