Diamondbacks decline mutual option on four-time All-Star reliever

The Diamondbacks have declined their side of a mutual option with veteran right-hander Mark Melancon, reports Steve Gilbert of MLB.com. The option was valued at $5M, but the Diamondbacks will instead opt to pay Melancon a $2M buyout on the option. The decision hardly comes as a surprise, both because mutual options are very rarely picked up and also because the 38-year-old righty did not pitch in 2023 due to a shoulder strain.

This was Melancon’s second season in Arizona, as the veteran righty initially signed with the club on a two-year, $14M deal prior to the 2022 season on the heels of a resurgent 2021 campaign that saw him post a 2.23 ERA in 64 2/3 innings of work while leading the majors with 39 saves as the primary closer in San Diego. Melancon figured to fill the closer role for Arizona in 2022, but struggled to find his footing with the club, ultimately posting a 4.66 ERA (13% below average by measure of ERA+) and 4.20 FIP with 18 saves as the club lost 88 games.

Perhaps even more concerning than the downturn in results was Melancon’s plummeting strikeout rate. While Melancon was never much of a strikeout artist throughout his career, posting strikeout rates above 25% just twice in his career, his 22.3 percent strikeout rate in 2021 was an almost perfect reflection of his 22.2 percent strikeout rate in his career to that point. Melancon’s punch outs plummeted in 2022, however, as he struck out just 14.2 percent of batters faced during his age-37 season, the lowest mark of his career outside of a 13-game cup of coffee he received with the Yankees as a rookie in 2009.

On the heels of a down season in 2022 and a lost season in 2023, it’s fair to wonder what’s next for Melancon. The veteran righty has had one of the strongest relief careers of his generation, with a career ERA of just 2.94 and 454 saves in 732 career games. At the same time, he’ll turn 39 on Opening Day 2024 and last pitched effectively when he was 36 years old. Given the constant need for bullpen depth around the majors, it seems likely that Melancon will be able to find a job this offseason should he wish to continue his career, but it seems likely he’ll be relegated to minor league deals given his lack of recent track record and uncertain health situation.

As for the Diamondbacks, the club has a fairly solid bullpen nucleus ahead of the 2024 campaign, with closer Paul Sewald backed up by the likes of Kevin Ginkel, Ryan Thompson and Andrew Saalfrank. That being said, it’s certainly feasible the club could look to bolster its bullpen depth given their 4.22 bullpen ERA in 2022, which ranked just 18th in the majors last year. Plenty of right-handed relievers figure to be available this season if Arizona is interested in replacing Melancon on the depth chart, with the likes of Jordan Hicks and Reynaldo Lopez chief among them.
