The Diamondbacks are finalizing a contract with right-hander Merrill Kelly, according to a report from Ken Rosenthal of The Athletic. Rosenthal adds that it’s a two-year, $40MM pact. Jon Heyman of The New York Post adds that the deal is pending a physical.
Kelly, 37, returns to the team with which he has spent nearly his entire major league career. Though initially drafted by the Rays in the eighth-round of the 2010 draft, Kelly made his big league debut with the Diamondbacks back in 2019 after a four-season stay in Korea as a member of the KBO’s SK Wyverns (now known as the SSG Landers). After a pedestrian rookie campaign in the majors where he pitched to a league-average ERA in 32 starts, Kelly managed to fashion a role for himself as one of the better mid-rotation arms in the majors.
Since the start of the 2022 campaign, Kelly has pitched to a 3.47 ERA (120 ERA+) in 108 starts. He’s struck out 23.1% of his opponents while walking 7.7% in that time, leaving him with a 3.81 FIP. While Kelly’s peripherals (including a 4.03 SIERA) cast him as a step down from your prototypical front-end starter, the veteran has managed to remain a quality rotation piece eating innings at a high level (with at least 175 innings of work in three of the last four seasons) and endeared himself to fans in Arizona when he delivered a brilliant 2.25 ERA during the club’s run to the World Series in 2023.
More to come.
