Joe Mantiply Re-Signs With Blue Jays on MiLB Deal

[Leo Morgenstern]

Veteran left-hander Joe Mantiply re-joined the Blue Jays today, signing a new minor league contract. Unsurprisingly, his deal includes an invitation to spring training.

Mantiply, now 35, was a late bloomer. Following several years in the Tigers, Yankees, and Reds organizations, he broke out in his thirties with the Diamondbacks. From 2021-24, he pitched in 236 games for Arizona, putting up a 3.63 ERA and 3.49 xERA. He did an exceptional job of keeping the ball on the ground and limiting home runs. More than half of the batted balls he allowed in those four years were on the ground, and he kept his opponents to just 12 home runs in 820 trips to the plate.

The lefty had a strong season in 2024 but struggled terribly in 2025. The D-backs optioned Mantiply in April after he gave up 13 runs and 20 hits over his first eight games. His struggles continued at Triple-A and in his brief return to the majors. Eventually, on June 1, the team for whom he made an All-Star appearance in 2022 and pitched meaningful postseason innings in 2023 released him, less than one year removed from a 75-game, 1.2 fWAR season. 

After six weeks in the wilderness, Mantiply found a new home in the Blue Jays organization. He looked much more like his old self over two months with Buffalo, producing a 3.45 ERA and 1.90 FIP in 15.2 innings, striking out 19, walking none, and giving up just one home run. 

Presumably, Mantiply was hoping to parlay that strong finish into a major league deal. Evidently, however, he was unable to land a guaranteed contract, so he chose to re-up with the organization that bought stock in him last summer. He will most likely start the season back at Triple-A, but if he performs anything like he did in his last stint in Buffalo, he'll get his chance in the big league bullpen eventually.

Sounds good to me. No risk. He was good in 2024.   Velo is dropping though so it's unlikely he'll return to that form.
