Mariners Confirm Key Deals as Seattle Locks In Three Core Pieces for 2026
SEATTLE — The Seattle Mariners have officially taken decisive steps to stabilize their roster ahead of the 2026 season, confirming deals involving three important contributors that address depth, bullpen dominance, and middle-of-the-order offense. The moves reflect a clear organizational plan: protect the core, reinforce key areas, and build continuity for another postseason push.
Andrew Knizner Signed to One-Year Deal
Seattle confirmed the signing of veteran catcher Andrew Knizner to a one-year major-league contract, a move designed to strengthen depth behind All-Star catcher Cal Raleigh.
Knizner brings experience, defensive reliability, and familiarity with managing pitching staffs — qualities the Mariners value as they look to maintain stability at the catching position throughout a long season.
“Andrew gives us exactly what we were looking for,” a team source said. “He’s experienced, prepared, and fits perfectly into the role behind Cal.”
The signing ensures the Mariners won’t overextend Raleigh while maintaining quality innings behind the plate in 2026.
Andrés Muñoz Option Exercised, Bullpen Anchor Returns
In another important announcement, the Mariners exercised their 2026 club option on closer Andrés Muñoz, securing one of the most dominant relievers in the American League for another season.
Muñoz’s triple-digit fastball and late-inning presence have made him a cornerstone of Seattle’s bullpen. By locking him in for 2026, the Mariners preserve continuity in high-leverage situations and send a clear message that bullpen strength remains a top priority.
“Keeping Muñoz was an easy decision,” a front-office source noted. “He’s a game-changer at the back end.”
Josh Naylor Extension Nearing Completion
Perhaps the most impactful move involves Josh Naylor, with the Mariners confirming they are close to finalizing a multi-year extension with the slugger acquired in 2025. Naylor quickly emerged as one of Seattle’s most reliable offensive weapons, combining power, intensity, and leadership.
Internally, Naylor has been viewed as a foundational hitter, and securing his long-term future has been at the top of the offseason agenda.
“He’s the kind of player you build around,” a team insider said. “This deal has been a priority from the start.”
A Clear Message From Seattle
Taken together, these moves highlight a focused and deliberate strategy by the Mariners’ front office: reinforce key positions without unnecessary risk while ensuring the clubhouse remains strong and competitive.
With Knizner adding depth, Muñoz anchoring the bullpen, and Naylor poised to remain a centerpiece of the offense, Seattle enters the heart of the offseason with momentum and clarity.
The Mariners aren’t just preparing for 2026. They’re positioning themselves to contend.
