Diamondbacks Reunite With Paul Sewald on One-Year Deal

The Arizona Diamondbacks are bringing back a familiar bullpen arm, agreeing to a one-year, $1.5 million contract with veteran right-hander Paul Sewald.

Sewald returns to Arizona after spending last season with Cleveland and Detroit, and the move reunites the club with a reliever who played a key role in its 2023 World Series run. To clear a 40-man roster spot, the Arizona Diamondbacks placed right-hander Justin Martinez on the 60-day injured list as he continues to recover from elbow surgery.

Revisiting the 2023 Postseason Run

Sewald arrived in Arizona at the 2023 trade deadline in a deal with the Seattle Mariners and quickly stepped into the closer role. He helped stabilize the bullpen down the stretch and recorded six saves during the postseason.

He was dominant through the first three playoff rounds, throwing eight scoreless innings before running into trouble in the World Series against the Texas Rangers. Despite the rough finish, his overall impact during that surprise National League pennant run cemented his value to the club.

Injuries and Decline in 2025

Now 35 and entering his age-36 season in May, Sewald is looking to rebound from an injury-affected 2025 campaign. He combined for a 4.58 ERA in 22 appearances with Cleveland and Detroit, missing time due to shoulder issues.

His average fastball velocity dipped to 90.4 mph last season, down from its 2023 peak, though he has continued to generate strikeouts at a respectable clip. The Diamondbacks are betting that improved health and a normal offseason can help restore some effectiveness.

Bullpen Help Needed in Arizona

Arizona’s bullpen endured heavy turnover and injuries last year, cycling through a league-record number of pitchers to record a save and finishing near the top of the National League in blown saves.

With Martinez sidelined and other key relievers working back from injuries, Sewald provides low-cost experience and late-inning depth. At $1.5 million, the risk is minimal for a team seeking stability in high-leverage situations.

For Sewald, the reunion offers familiarity and opportunity. For the Diamondbacks, it’s a practical move aimed at steadying a bullpen that needs reliable innings as it pushes to contend again in 2026.
