Diamondbacks Bullpen Upgrade: Top Free Agent Relievers Still Available for 2026 (2026)

The Arizona Diamondbacks are in a bullpen bind, and it's a situation that's got fans and analysts alike scratching their heads. But here's where it gets controversial: with the reliever market heating up, why haven't the Diamondbacks made a significant move yet?

The offseason has seen a flurry of activity in the reliever market, with big names like Edwin Diaz, Devin Williams, and Kenley Jansen finding new homes. Yet, the Diamondbacks, who clearly need bullpen help after a disastrous 2025 campaign, have only signed starters Merrill Kelly and Michael Soroka. General Manager Mike Hazen assures fans they're actively engaged in the market, but as of Christmas Eve, no major league reliever has been added to the roster.

And this is the part most people miss: the Diamondbacks have been strategic in their approach, focusing on minor league deals that have yielded success in the past, such as Shelby Miller and Juan Morillo. This offseason, they've signed Taylor Rashi, Gerardo Carrillo, Isaiah Campbell, and John Curtiss, among others. But with 14 of the top 16 relievers already off the board, the question remains: who's left?

The trade market is always an option, and names like Alek Thomas, Jake McCarthy, and Ketel Marte have been floated around. However, the free agent market still has some intriguing options, including:

  • Pierce Johnson (34): A solid performer with a nasty curveball, Johnson had a 3.05 ERA in 59 innings last season. While his metrics aren't eye-popping, he's been reliable, especially in high-leverage situations.
  • Jonathan Loáisiga (31): Despite an impressive resume, including a 96-98 mph fastball and a 3.36 ERA from 2019-2025, Loáisiga's injury history is a concern. He's a high-ceiling, low-floor option.
  • Tyler Kinley (34): After a rough stint in Colorado, Kinley thrived with the Braves, posting a 0.72 ERA in 25 innings. His slider is a weapon, but his career has been inconsistent.

Here's a bold interpretation: The Diamondbacks might be waiting for the market to cool down or for a trade opportunity to present itself. But with the season approaching, time is ticking. Are they being too cautious, or is this a calculated risk?

Other notable free agents include Michael Kopech (29), Seranthony Dominguez (31), Danny Coulombe (36), and Kirby Yates (38), each with their own unique strengths and weaknesses. The Diamondbacks have a tough decision to make, and it's one that could shape their 2026 season.

Thought-provoking question: With the reliever market thinning out, should the Diamondbacks prioritize proven veterans or take a chance on younger, high-upside arms? Share your thoughts in the comments, and let's spark a discussion!
