Diamondbacks Set to Sign Veteran Pitcher Merrill Kelly

The Arizona Diamondbacks are set to bring back veteran pitcher Merrill Kelly. The team and Kelly have agreed to a two-year deal worth $40 million, pending a medical check. Once completed, Kelly will return to the team where he has spent most of his career.

Kelly, 37, first joined the Diamondbacks in 2019 after playing four seasons in South Korea. He became a reliable starter for the team and earned a strong reputation for pitching deep into games. Fans quickly grew to appreciate his consistency and experience.

 

In 2025, Kelly spent part of the season with the Texas Rangers after being traded at the midseason deadline. However, both Kelly and Arizona hinted that a reunion could happen. Now, that reunion is about to become official.

The Diamondbacks hope Kelly will strengthen their starting rotation for the 2026 season. His experience and leadership are expected to help guide a pitching staff that needs stability. Many see him as an important addition as the team looks to compete in the tough National League West.

Fans are excited to see Kelly return. They remember him as a steady presence on the mound who can give the team quality innings. His return also adds depth to Arizona’s pitching staff, which will be important as the team tries to reach the playoffs.

If he passes his medical exam, Kelly will play a key role for the Diamondbacks over the next two seasons. The team hopes his experience and steady pitching will help them succeed and make a push for the postseason.
