Seattle Mariners Unveil 2026 Opening Day Roster with Surprises

The Seattle Mariners have officially revealed their 2026 Opening Day roster, showcasing a blend of expected names and a few surprising inclusions. Despite a relatively healthy Spring Training, the Mariners will begin the season without starting shortstop J.P. Crawford and right-handed pitcher Bryce Miller, both of whom are on the injured list. Fortunately for the team, both players are anticipated to return early in April, opening the door for some depth pieces to step up in their absence. Additionally, utility player Miles Mastrobuoni will also start the season on the injured list.

Behind the plate, Cal Raleigh has secured the starting catcher position, edging out Andrew Knizner and Jhonny Pareda for the role. The Mariners designated Knizner for assignment to make room for Raleigh, ensuring that Pareda remains the next option in Tacoma if needed. This move reflects the team’s confidence in Raleigh’s abilities to guide the pitching staff.

Infielder Ryan Bliss has emerged as a surprising addition to the roster, having solidified his spot through a strong spring performance. A month ago, Bliss’s chances seemed slim, but injuries to Crawford and Mastrobuoni allowed him to outlast top prospect Colt Emerson, who has been optioned back to Triple-A Tacoma. Both Leo Rivas and Cole Young will share shortstop duties until Crawford’s return, showcasing the Mariners’ commitment to developing their infield talent.

Utility player Brendan Donovan adds versatility, capable of covering multiple positions on the diamond, though shortstop may be a stretch. Luke Raley’s return from injury is a significant boost, as he can competently handle all outfield spots, enabling more designated hitter opportunities for Randy Arozarena. Rob Refsnyder presents a unique challenge defensively, having played various infield positions but primarily first base in recent years. His role is primarily as a hitter, bolstered by the versatility of his teammates.

The outfield remains a strong point for the Mariners, featuring a talented group that includes Randy Arozarena, Dominic Canzone, Victor Robles, and Julio Rodríguez. This unit is poised to be the most formidable since the days of Ichiro Suzuki and Mike Cameron.

On the pitching front, the starting rotation is set with Logan Gilbert, George Kirby, Bryan Woo, Luis Castillo, and Emerson Hancock. The Mariners are optimistic about Miller’s return, hoping it will occur within weeks without disrupting his preparation.

The bullpen sees the addition of two new faces: José A. Ferrer and Cooper Criswell. Ferrer, acquired in a trade involving catcher Harry Ford, is expected to contribute as a high-leverage arm. Criswell brings a mix of starting and relief experience, slotting into a long relief role. While Casey Legumina and Carlos Vargas struggled last season, their lack of minor league options has kept them on the roster for now. The Mariners are likely to see stability in their core bullpen group while remaining flexible to changes as health issues arise.
