Jon Duplantier
25-Year-Old PitcherRP
2019 Fantasy Outlook
Duplantier is among the most skilled pitchers in the minor leagues, but durability is a big question mark. After he managed to throw 136 innings in 2017, that number fell to just 74 this past season as Duplantier dealt with hamstring and, more notably, biceps issues. This came after Duplantier missed the entire 2015 season with a shoulder injury and after he battled elbow soreness during his first year of pro ball in 2016. He made up for some lost time this past year in the Arizona Fall League, throwing 21.2 innings and fanning 32 against some of the most polished hitting prospects in the game, but in the end he was still under the century mark in total. His slider is an impressive swing-and-miss pitch and Duplantier can get both strikeouts and groundballs with the heater. Add in plus command and Duplantier has clear mid-rotation potential, but consider us skeptical that he can hold up to the rigors of a major-league season year-in and year-out. Read Past Outlooks

Shines in long relief
PArizona Diamondbacks
September 25, 2019
Duplantier tossed three scoreless frames in relief Tuesday in the Diamondbacks' 3-2 win over the Cardinals in 19 innings. He scattered three hits and struck out two in the appearance.
ANALYSIS
Arizona had 12 relievers combine to shut out the Cardinals over the 13 innings, with Duplantier working the longest out of all those bullpen arms. The Diamondbacks still appear to view Duplantier as a rotation option over the long haul, but he'll continue to work in relief during the season's final week as the organization looks to manage his innings count.

Stat Review
How does Jon Duplantier 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.

2018 Fantasy Outlook
Most pitchers from Rice are overused to the point that they are shells of themselves once they get into pro ball. This, coupled with the fact that he dealt with a shoulder injury in 2015, is how Duplantier fell to the Diamondbacks in the third round in 2016. So far the 6-foot-4 righty has been better than anyone could have imagined. He led qualified minor-league pitchers with a 1.39 ERA across stops at Low-A and High-A last year -- the second lowest minor-league ERA over the last 25 years, trailing only Justin Verlander's 1.29 mark from 2005. Duplantier commands a plus fastball, two potentially above-average breaking balls in his slider and curveball, and an average changeup. That pitch mix, while deep, doesn't quite match his absurd production. Considering he turns 24 in July and will be making his Double-A debut this year, it's too early to say he has frontline upside. A better bet is that he struggles at times in the upper levels and settles in as a mid-rotation starter.
