Kansas City sent several of its top prospects back to minor-league camp Monday, as Kowar was reassigned along with infielder Bobby Witt, outfielder Kyle Isbel and pitcher Daniel Lynch. Kowar will likely open the 2021 campaign at Triple-A Omaha after posting a 3.51 ERA, 1.27 WHIP and 78:21 K:BB across 74.1 innings at Double-A Northwest Arkansas in 2019.
