PHOENIX, AZ — In a shocking MLB move this morning, Paul Sewald, the former star shooter who was once the Seattle Mariners’ last line of defense, officially signed a one-year contract with the Arizona Diamondbacks — the team he helped make a surprise World Series appearance in 2023. This is no ordinary trade — for Mariners fans, it’s a poignant farewell from one of their closest companions over the years.
At 35, Sewald was once the number one hope when the game went into the final quarter, with his powerful shooting style and unwavering fighting spirit. But now, after many seasons battling it out — from the Mariners to the Cleveland Guardians and then the Detroit Tigers — he is preparing to return to Arizona with a different mindset: both as a strategic contributor and as the beginning of a new chapter in his career.
Immediately after the trade was announced, Sewald sent a message that touched the hearts of Mariners fans:
“I will always carry the wonderful memories of Seattle with me. Those days wearing the Mariners uniform — those were the times I felt most loved in my career. I want to thank all the fans who have been with me, believed in me, and cheered me on. Wherever I go next, the Mariners will always be an important part of my journey.”
This message quickly spread on social media, stirring up emotions among the Mariners fan community. Many fans called it a “true farewell moment,” as an indispensable warrior of the team once said goodbye in the most empathetic and profound way.
Sewald will sign a one-year, $1.5 million contract with the Diamondbacks, marking his return to the team that took him to the World Series — where he made his mark with several crucial saves and consistent performance in the 2023 postseason.
Throughout the 2025 season, Sewald had a difficult time splitting his playing time between the Guardians and Tigers, recording only 2 saves and 4.58 ERA in 22 appearances, before becoming a free agent again.
Now, his reunion with the Diamondbacks is not just a “return to his old home,” but also an opportunity to revive his career, contribute to a young, ambitious bullpen force, and transform the Diamondbacks into a National League contender in 2026.
For the Mariners, Sewald’s departure marks the departure of a bullpen legend from the team he served from 2021 to 2023 — a period in which he recorded 34 individual saves in the 2023 season, making a significant contribution to the team’s success.
His absence leaves many Mariners fans feeling empty, as if they’ve lost a member of their baseball family. On fan forums, posts expressing gratitude and regret are constantly appearing, as they recall Sewald’s crucial clean sheets and the times T-Mobile Park erupted when he stepped onto the mound.
Although the contract is only for one year, experts believe Sewald can use it as a springboard to rebuild his value. Upon returning to the Diamondbacks, he faces the opportunity to:
Re-establish his form after a challenging season.
Become a key player in helping the D-backs maintain their bullpen momentum.
AIM for a championship he almost achieved before.
With his strong defensive skills and extensive experience, Sewald could still be one of the most influential shooters on the free agency this season.
More than just a trade, Sewald’s reunion with the Diamondbacks and his sweet farewell to the Mariners has created a story of gratitude, loyalty, and a spirit that transcends statistics.
Those who loved him will remember not only his powerful elbow throws and breathtaking games, but also the moments Sewald thanked his fans—as friends, as comrades, as their own legend.
For Seattle, it was a bittersweet farewell. But for Sewald, it was just the next chapter of an extraordinary journey.
