Seattle Mariners Reveal 2026 Opening Day Roster

The Seattle Mariners have revealed their roster for Opening Day in 2026, showcasing a blend of expected starters and some notable absences due to injuries. As the season kicks off, the team has navigated Spring Training with relatively few health issues, yet key players like starting shortstop J.P. Crawford and right-handed pitcher Bryce Miller will not be available at the start. Their return is anticipated in early April, prompting opportunities for other players to step up.

Injuries Impacting the Roster

Along with Crawford and Miller, utility player Miles Mastrobuoni will also begin the season on the injured list. This situation has led to alterations in the Mariners’ lineup.

Key Player Promotions

Cal Raleigh and Mitch Garver headline the catcher position, with Garver prevailing over Andrew Knizner and Jhonny Pareda for the primary role. The Mariners have designated Knizner for assignment to make room for Garver, while Pareda will provide depth at Triple-A Tacoma.

• Cal Raleigh – Brought expertise to the position.
• Mitch Garver – Outperformed competitors in Spring Training.
• Andrew Knizner – Designated for assignment.
• Jhonny Pareda – Will be available on the roster in Tacoma.

Surprising Additions and Shifts

Infielder Ryan Bliss, who seemed unlikely to make the roster initially, has secured a position due to a strong performance and the injuries faced by others. With top prospect Colt Emerson optioned to Triple-A, Bliss will join Cole Young and Leo Rivas, who will cover shortstop until Crawford returns.

Utility and Outfield Players

The Mariners have also reinforced their utility spots with Brendan Donovan, Luke Raley, and Rob Refsnyder. Donovan offers flexibility across the diamond, while Raley’s recovery enhances the outfield’s depth. Refsnyder, despite questions about his defensive fit, provides added versatility and experience.

Star Outfielders and Starting Pitchers

The outfield lineup features standout players including Randy Arozarena, Dominic Canzone, Victor Robles, and Julio Rodríguez, regarded as one of the strongest outfield groups in Mariners history.

The starting rotation includes Logan Gilbert, George Kirby, Bryan Woo, Luis Castillo, and Emerson Hancock, with Miller’s return expected soon. The bullpen will comprise Eduard Bazardo, Matt Brash, Cooper Criswell, José A. Ferrer, Casey Legumina, Andrés Muñoz, Gabe Speier, and Carlos Vargas, with Ferrer being a noteworthy addition.

The Mariners appear poised for an exciting season ahead, with depth in various positions and a strategy that reflects both resilience and adaptability. As they head into Opening Day, the team will look to maximize their roster potential in light of the injuries.
