Diamondbacks Officially Sign Merrill Kelly to Two-Year Deal

The Arizona Diamondbacks have officially signed right-handed pitcher Merrill Kelly to a two-year contract valued at $40 million. This announcement comes after prior reports hinted at the agreement, which includes a vesting option for the 2028 season. If Kelly pitches more than 170 innings during the contract period, an additional $12 million will be triggered. Should he exceed 185 innings, a figure he has only reached once throughout his career, the amount increases to $14 million.

Kelly returns to the Diamondbacks after a brief period away from the organization. During the 2025 season, he was traded to the Texas Rangers at the deadline, where he made only 10 starts and recorded a 4.23 ERA. While this performance was below his established standard with Arizona, it highlights the importance of stability in a pitching staff that has faced challenges.

Reinforcing the Rotation

As Kelly enters his age-37 season, the signing carries inherent risks. Nevertheless, he has proven to be a reliable presence in the Diamondbacks’ rotation, earning the nickname “Mainstay.” Over his career, Kelly has maintained a respectable 3.77 ERA with consistent peripheral statistics. His ability to deliver quality innings makes him a crucial asset for a team that has struggled to find dependable pitching.

The Diamondbacks have prioritized securing reliable innings coverage during the offseason. With Kelly back in the fold, the team gains not only stability but also the potential for standout performances. His track record shows that he rarely has poor outings, and he can typically be counted on for more than five innings of solid work, even on off days.

A Promising Future

While the Diamondbacks’ pitching staff still requires further strengthening, the return of Kelly is a reassuring development. His experience and steadiness offer hope for improvement as the team prepares for the upcoming season. As the Diamondbacks look to enhance their competitive edge, Kelly’s presence in the rotation could play a pivotal role in their success. Fans and analysts alike will be watching closely to see how this veteran pitcher impacts the team’s performance in the years ahead.
