Joe Mantiply - MLB News, Rumors, & Updates

Inks deal with Toronto Mantiply signed a minor-league contract with the Blue Jays on Tuesday that includes an invite to big-league spring training.

Impact The 35-year-old lefty spent the previous six seasons with the Diamondbacks but was released last June. Mantiply then inked a minor-league pact with Toronto in July. He appeared in 14 games out of the bullpen for Triple-A Buffalo, posting a 3.45 ERA, 1.21 WHIP and 19:0 K:BB across 15.2 innings but didn't appear in any big-league games for the Blue Jays. Mantiply will compete for one of the final spots in the bullpen ahead of Opening Day.

DFA'd by Snakes The Diamondbacks designated Mantiply for assignment Friday.

Mantiply was sent down to Triple-A on May 15 after posting a 15.83 ERA and 3.00 WHIP across 9.2 major-league innings. He hasn't fared that much better in Triple-A with a 5.56 ERA and 1.53 WHIP in 11.1 innings.

Back in Arizona The Diamondbacks recalled Mantiply from Triple-A Reno on Saturday.

Impact Mantiply has given up 13 runs in only 7.1 innings with the D-backs this season, but he's only allowed two runs in six frames since being sent down to Triple-A. He'll get another look in the majors as a replacement for Cristian Mena, though it's unlikely Arizona uses Mantiply outside of low-leverage situations.

Sent down to Reno The Diamondbacks optioned Mantiply to Triple-A Reno on Saturday.

Impact Mantiply has struggled mightily in the big leagues this season, giving up 13 earned runs in just 7.1 innings. He'll attempt to get back on track in Triple-A, though the D-backs will likely need to see him sustain success for an extended period of time before feeling comfortable inserting him back into their bullpen.

ERA on the rise Mantiply allowed two runs on four hits and one walk while striking out one over one inning in Tuesday's 10-4 win over the Marlins.

Impact The Diamondbacks were leading, 10-1, when Mantiply opened the seventh inning, so the run allowed didn't jeopardize the club, but the left-hander hasn't executed thus far. He isn't overpowering, so he needs to be precise with location. Mantiply's given up runs in his last three outings, pushing his overall ERA to 13.50 over 6.2 innings (seven outings).

Added to closer mix In discussing Arizona's closer role, manager Torey Lovullo mentioned Mantiply as someone that could get save opportunities, Alex Weiner of Arizona Sports reports. "I don't want to...

Impact Lovullo feels all the candidates to close, which prior to mentioning Mantiply, included Kevin Ginkel, Justin Martinez and A.J. Puk, have thrown well this spring. There's still a handful of Cactus League games the manager can use to evaluate, but this process could play out into the regular season. Mantiply has a 1.35 ERA with three walks and three strikeouts over 6.2 spring innings.

Avoids arbitration with Arizona Mantiply and the Diamondbacks avoided arbitration by agreeing to a one-year, $1.7 million contract Thursday, Kiley McDaniel of ESPN.com reports.

Impact Mantiply finished the 2024 regular season with a 6-2 record across 75 appearances (including two starts) and posted 16 holds, 3.92 ERA and 1.17 WHIP across 59.2 innings while registering an 8.0 K/9. The 33-year-old out of Virginia Tech will provide the Diamondbacks with a southpaw option out of the bullpen for the 2025 campaign.
