The Diamondbacks released lefty Joe Mantiply<\/a> after his recent DFA, per their transaction log at MLB.com<\/a>. Assuming he clears release waivers, he\u2019ll be a free agent who can sign with any team tomorrow afternoon.<\/p>\n

Mantiply, 34, has been a frequent presence in Arizona\u2019s bullpen dating back to 2021. From \u201921-\u201924, he pitched 198 1\/3 innings with a 3.63 ERA, a 22% strikeout rate, a 6.1% walk rate, a 51.9% grounder rate, 50 holds and three saves. In 2022, specifically, he was one of the team\u2019s most frequently used relievers in high-leverage spots.<\/p>\n

The 2025 season has been an abject disaster for Mantiply, however. He fired a perfect inning in his first appearance of the season and immediately tanked thereafter. By the time Arizona optioned Mantiply to Triple-A Reno on April 19, he\u2019d been tagged for a calamitous 13 runs in just 7 1\/3 innings across eight relief outings. He got another look in mid-May and was quickly optioned again after surrendering four runs in 2 1\/3 innings.<\/p>\n

Even Mantiply\u2019s time in Triple-A was generally a struggle. He allowed four runs in his first appearance with Reno and five in his final one. Those ugly outings bookended a strong run of 9 2\/3 shutout innings, but the overall results were grim. In 9 2\/3 MLB frames this year, Mantiply has a 15.83 ERA. He\u2019s posted a 5.56 mark in 11 1\/3 Triple-A innings.<\/p>\n

Mantiply has always been a soft-tosser, but his fastball has bottomed out in 2025, averaging a career-low 88.2 mph. He sat 91.3 mph with the pitch back in 2021-22, when he was at his best, and was at 89.5 mph last year. He\u2019s still filling up the strike zone, but doing so with diminished stuff has yielded diminished returns.<\/p>\n

By all accounts, Mantiply is healthy at the moment. Teams are always in need of left-handed bullpen help, and Mantiply has a generally solid track record in the majors, so he ought to get another chance to turn his season around with a new club before too long. He\u2019ll almost certainly need to pitch his way back to the majors on a minor league deal, however. He\u2019s being paid $1.7MM this year, and the D-backs will remain on the hook for the rest of that salary \u2014 minus the prorated minimum for any team he spends with another club\u2019s big league roster.<\/p>\n","protected":false},"excerpt":{"rendered":"The Diamondbacks released lefty Joe Mantiply after his recent DFA, per their transaction log at MLB.com.
