Stat Review
How does Joe Mantiply compare to other relievers?
This section compares his stats with all relief pitcher seasons from the previous three seasons (minimum 30 innings)*. The bar represents the player's percentile rank. For example, if the bar is halfway across, then the player falls into the 50th percentile for that stat and it would be considered average.
* Exit Velocity, Barrels/BBE %, Balls Hit 95+ MPH %, and Spin Rate are benchmarked against 2019 data (min 30 IP). See here for more exit velocity/barrels stats plus an explanation of current limitations with that data set.

Past Fantasy Outlooks
2025
2023
2017
Mantiply was hurt early in 2023 which played a role in a down season, but a strong September portended a bounce back in 2024. His 3.92 ERA and 41.9 hard-hit percentage last season doesn't scream success, but a 2.51 FIP indicates bad luck was at play. The lefty is consistently capable of inducing groundballs - 54.1 groundball rate in 2024 and 53.2 for his career - and limiting home runs. Entering his age-34 season, Mantiply does not overpower hitters and relies on a diet of sinkers, curveballs and changeups. If healthy, he'll earn a spot in the bullpen, where he'll work anywhere between the sixth and eighth innings while occasionally facing a difficult lefty to the final out of an inning.

Latest Fantasy Rumors
Skidding of late
Mantiply has limped to a 4.76 ERA over his past seven appearances. The 31-year-old still carries a 2.86 season-long ERA with quality peripheral metrics.
Analysis
He has begun righting the ship, but Mantiply allowing eight earned runs over his last 11 innings marked a sizably blemish. Mantiply is seemingly in the mix to earn save opportunities down the stretch. His relative youth compared to Arizona's other options bode well for his future closer status as well. Mantiply owns an excellent 0.8 BB/9 and has strong swing-and-miss stuff that has helped him enjoy a breakout year.
