Arizona Diamondbacks Bullpen: Embracing Change and Challenges
The Arizona Diamondbacks are entering the new season with a bold strategy for their bullpen-no left-handers in sight. After a tumultuous 2025 season where 17 different pitchers recorded saves, breaking an MLB record, manager Torey Lovullo and GM Mike Hazen are ready to shake things up.
Despite boasting a top-10 offense, the Diamondbacks’ bullpen struggled, finishing in the bottom five for ERA, WHIP, and strikeouts per nine innings. Addressing this weakness became a priority for Hazen during the offseason. "We want to increase the stuff that’s out there," Hazen emphasized, focusing on boosting the bullpen's depth and swing-and-miss potential.
Lovullo took a competitive approach during spring training, stating that all bullpen spots were up for grabs. "Earn it. Nothing is going to be handed to you," he declared, setting the tone for a merit-based selection process.
As the team finalized its roster, eight right-handed relievers emerged victorious. This marks the first time in Lovullo and Hazen’s decade-long tenure that no lefties are in the bullpen.
Lovullo is confident in his decision, citing the effectiveness of right-handers with reverse splits against left-handed hitters. "I want trusted relievers who fill up the strike zone and create weak contact," he explained.
Injuries also influenced the bullpen's composition. Left-handers A.J.
Puk and Andrew Saalfrank are sidelined with significant injuries, leaving them unavailable for the start of the season. Lovullo aims to manage workloads carefully to avoid a repeat of last year’s injury woes.
"We might adjust usage early on so these guys can step on the gas pedal later," he noted.
The closer role is still up for grabs, with several candidates in the mix. Paul Sewald, a familiar face, returns to Arizona after a successful stint in 2023.
Known for his clutch performances, Sewald is a strong contender. Ryan Thompson and Kevin Ginkel, both experienced in closing games, add depth and reliability to the bullpen.
Meanwhile, Jonathan Loáisiga, a new addition from the Yankees, brings tantalizing potential with his high-velocity fastball and strikeout ability.
The Diamondbacks' unconventional bullpen will face an immediate test against the Los Angeles Dodgers, the reigning World Series champions. Lovullo’s strategic handling of LA’s formidable left-handed hitters, including Shohei Ohtani, Kyle Tucker, and Freddie Freeman, will be critical.
As the season unfolds, all eyes will be on how this unique bullpen setup performs. The Diamondbacks are betting on their right-handed depth and versatility to navigate the challenges ahead, aiming to turn last year’s struggles into this season’s success.
