The Seattle Mariners announce their 2026 Opening Day roster

Key Points:

• The Seattle Mariners' 2026 Opening Day roster includes some surprises, notably the absence of starting SS J.P. Crawford and RHP Bryce Miller due to injuries, with both expected to return in early April. UTIL Miles Mastrobuoni is also out injured to start the season.
• Catcher Mitch Garver secured the backup role over Andrew Knizner and Jhonny Pareda, likely leading to Knizner being designated for assignment, while infielders Ryan Bliss, Josh Naylor, Leo Rivas, and Cole Young fill in until Crawford returns, with prospect Colt Emerson optioned to Triple-A Tacoma.
• The utility and outfield positions feature versatile players like Brendan Donovan, Luke Raley, and Rob Refsnyder, with Refsnyder primarily valued for his hitting despite defensive limitations; the outfield boasts a strong group including Randy Arozarena, Dominic Canzone, Victor Robles, and Julio Rodríguez.
• The starting rotation remains as expected with Logan Gilbert, George Kirby, Bryan Woo, Luis Castillo, and Emerson Hancock, while the bullpen includes two new faces: José A. Ferrer, a high-leverage lefty acquired in the offseason, and Cooper Criswell, filling a long relief role, alongside returning arms to maintain stability.
• Overall, the Mariners’ roster reflects a balance of health-related adjustments and strategic depth, with a potent bench and a strong outfield lineup signaling optimism for the upcoming season.
