Cox will be a part of the Royals' 60-man player pool this season, Enrique Rojas of ESPN Deportes reports.
One of the more underrated pitching prospects in the minors, Cox has arguably the best command and control of any of the Royals' top pitching prospects, and he has a deep, quality arsenal. He has never pitched above High-A, so he is unlikely to play a major role in 2020, but he could have a very bright future.
