Merrill Kelly, the veteran right‑hander who helped Arizona reach the World Series, has agreed to return to the Diamondbacks on a $40 million, two‑year contract.
Deal Details
The agreement, announced on Sunday, is pending a physical and has not yet been made public. A source familiar with the transaction, who requested anonymity, confirmed that the deal is still in the approval stage.
Career with Arizona and Texas
Kelly spent the first 6½ years of his career with the Diamondbacks before being traded to the Texas Rangers at the July trade deadline. Across both teams he posted a combined 12‑9 record and a 3.52 ERA. The 37‑year‑old was a key contributor in Arizona’s 2023 season, going 12‑8 with a 3.29 ERA.

World Series Highlight
During the 2023 World Series, Kelly delivered a masterful performance in Game 2 against the Rangers, the only victory the Diamondbacks earned in the Fall Classic. His ability to keep hitters off balance with a six‑pitch mix earned him fan acclaim.
Roots in Arizona
A native of Scottsdale, Kelly played college baseball at Arizona State. He made his Major‑League debut at age 30 in 2019, a rare late start that did not hinder his success.
International Experience
Before reaching the majors, Kelly was drafted by the Tampa Bay Rays in 2010 but remained in Triple‑A. He then signed with the SK Wyverns of the Korean Baseball Organization, where from 2015 to 2018 he compiled a 48‑32 record and a 3.86 ERA.
Past Contracts with the Diamondbacks
Arizona first signed Kelly to a $14.5 million, four‑year contract in 2018. In 2022, he agreed to an $18 million, two‑year deal covering the 2023 and 2024 seasons, which included a club option for 2025 that the Diamondbacks exercised.
Significance of the Return
Kelly’s return is not only a homecoming for a hometown favorite but also a strategic move for a team that values his reliable pitching. The $40 million, two‑year commitment underscores the organization’s confidence in his continued contributions.
