EDGE Analysis
The 23-year-old righty spent the year as part of the Nationals' player pool but did not get into the game, hardly a surprise as he spent the entirety of 2019 at the Low-A level. The timing of the surgery means he'll miss the entirety of the 2021 season but should be ready to go for spring training in 2022.
