Joan Adon

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
