Biographical Information

Joe Mantiply was an expert at posting low ERA's in the minors, with a 2.73 career minor league ERA in six seasons through 2019. He came to the majors twice during that period, with the Detroit Tigers in 2016 and the New York Yankees in 2019. In 2018 he was out for the season after undergoing Tommy John surgery.

Joe was also in the Cincinnati Reds organization for 1 3/4 seasons, from 2017 to 2019, but did not come to the majors with them. He was roughed up to the tune of a 15.43 ERA in 4 games with the Arizona Diamondbacks in 2020 before finally establishing himself as a major league pitcher with Arizona in 2021. That year, he pitched 57 games as a LOOGY, going 0-3, 3.40 while logging 39 2/3 innings. He was a surprise member of the National League roster at the 2022 All-Star Game, entirely thanks to the rule that every team must be represented at the game by at least one player. The D-Backs had a terrible first half that season, and he was one of the few players with decent numbers - albeit in a marginal role. He went 2-5, 2.85 in 69 games that season, recording his first two career saves. He posted an excellent K/W ratio of 60/6 in 61 innings.

In 2023, he had a rougher season, making 35 appearances including 3 starts as an opener, and logging 39 innings. He went 2-2, 4.62, but the Diamondbacks sneaked into the postseason, and once there, caught fire, making it all the way to the World Series. He wont two games in the first two rounds of the postseason, not giving up a run in 3 appearances, but in the NLCS against the Philadelphia Phillies, he gave up 4 runs in 2 2/3 innings. He was used as an opener in Game 4 on October 20th, pitching a scoreless 1st inning, and again in Game 4 of the World Series against the Texas Rangers on October 31st. In that game, he gave up a run in an inning and a third before giving way to Miguel Castro. The pitchers who succeeded him were roughed up, with Castro, Kyle Nelson and Luis Frias all giving up three runs, but he was the one charged with the 11-7 loss as Texas scored five runs in the 2nd and was leading 10-0 by the end of the 3rd inning.

In 2024, he pitched a career-high 75 games for the Diamondbacks, who barely missed out on the postseason (their record tied them with the New York Mets for the final spot, but the Mets held the tiebreaker). He went 6-2, 3.92, made a couple more starts as an opener, and pitched 59 2/3 innings, as he reverted back to a more classic LOOGY role. He picked up one save, only the third of his career, and his walk rate shot up, as the 18 he issued were the most of his career. However, things completely fell apart for him in 2025 as in his first 10 games, he gave up 17 runs on 26 hits in 9 2/3 innings, for an ERA of 15.83. He was optioned to AAA twice during the first two months of the season, then was released on June 1st. A month and a half later, on July 13th, he was signed by the Toronto Blue Jays who assigned him to the FCL Blue Jays to see if he could regain his past form.

He was drafted out of Virginia Tech, the same year as Chad Pinder was. The Philadelphia Phillies took him in the 27th round in the 2013 amateur draft, the third time he had been drafted, after Pinder had been taken in the 2nd round.

He is one of the very few players whose last name starts with the same four letters as Mickey Mantle's does. The list also includes Felix Mantilla, Jeff Manto and Matt Mantei.
