The Diamondbacks have agreed to a deal with lefty reliever Anthony Gose, reports Jon Heyman of the New York Post. Gose has spent the season thus far with the Mets organization, but the MiLB transaction log reflects that he was quietly released yesterday. Whether that was an opt-out clause, an upward mobility clause or a straight release remains to be seen, but Gose is headed to a new organization. If it’s a big league deal, the Diamondbacks will need to make a corresponding move, as their 40-man roster is currently at capacity. The team has not yet formally announced the signing.
Gose, 34, began his career as an outfielder back in 2008, when the Phillies selected him in the second round of the draft. He quickly became one of the game’s top prospects and wound up seeing action in parts of five major league seasons as an outfielder — all between the Blue Jays and Tigers. Gose’s career looked to have stalled out, but the former two-way star in high school reinvented himself as a relief pitcher back in 2017-19 and has now pitched in parts of three MLB seasons — all with Cleveland.
Gose made his major league debut as a full-time pitcher in 2021 and has now pitched 32 MLB frames with a 4.78 ERA, a 29.7% strikeout rate and a 12.3% walk rate. Injuries, most notably Tommy John surgery, have limited his time on the mound and impacted him when healthy. He’s also missed time with a triceps strain, a calf strain and shoulder soreness since moving to the mound.
Between those injuries and the fact that he’s now approaching his 35th birthday, perhaps it shouldn’t be all that surprising that Gose’s heater has lost some life. When he first moved to the mound, he was brandishing a blazing four-seamer that averaged better than 99 mph and reached triple digits at times. He sat 95.7 mph in both Triple-A and the big leagues last year, and he’s dipped further to an average of 94.6 mph in 2025.
Gose has pitched 23 innings with the Mets’ affiliate in Syracuse and logged a 4.30 ERA, 24.5% strikeout rate, 13.7% walk rate and 30.6% ground-ball rate. He started the season pitching quite well, yielding a 3.31 ERA through his first 16 1/3 innings, but he’s been hit hard over the past few weeks; dating back to May 17, Gose pitched in six games and was rocked for seven runs (five earned) on nine hits and three walks with seven strikeouts.
The D-backs are starved for arms, having recently lost Justin Martinez to Tommy John surgery, Christian Montes De Oca to back surgery and Kendall Graveman to a hip injury. Lefty A.J. Puk has been out since early April due to elbow troubles. Over in the rotation, Corbin Burnes recently suffered a UCL tear that necessitated Tommy John surgery as well. The D-backs have added righties Anthony DeSclafani and Tayler Scott in recent weeks, and Gose will now add another left-handed option to the depth chart.
