Joan Adon

24-Year-Old PitcherSP
Washington Nationals AAA
2023 Fantasy Outlook
Adon was a surprise addition to the Nationals' 2022 Opening Day rotation, but he struggled to a 7.10 ERA and was not seen again at the major-league level after July 7. Dress in layers if you're to visit Adon's Statcast page -- there is a lot of frigid blue, showing bottom-10 percentile ranks in xERA, xBA, xSLG, Barrel%, BB% and Whiff%. Things got better with Triple-A Rochester from a run-prevention standpoint (4.68 ERA), but Adon remained far too generous with the free passes (5.1 BB/9). Mostly a fastball-curveball pitcher last season, Adon brings good velocity with the heater. The Nationals may need him to eat innings in 2023 after he cleared 100 frames between the two levels a season ago. The 24-year-old remains on the 40-man roster as of late December. Read Past Outlooks

March 7, 2023
The Nationals optioned Adon to Triple-A Rochester on Tuesday, Jessica Camerato of MLB.com reports.
ANALYSIS
Adon posted a dreadful 7.10 ERA over 14 starts for the Nationals last season and wasn't viewed as a serious candidate for the Opening Day rotation. The right-hander has displayed plenty of bat-missing ability on the farm but still needs to fine-tune some things before getting another look in the majors.

Stat Review
How does Joan Adon compare to other starting pitchers?
This section compares his stats with all starting pitcher seasons from the previous three seasons (minimum 120 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 120 IP). See here for more exit velocity/barrels stats plus an explanation of current limitations with that data set.
