The Royals recalled Kowar from Triple-A Omaha on Tuesday.
Kowar holds a 7.84 ERA and 2.13 WHIP through 20.2 innings across 13 appearances in Omaha this season. His struggles are nothing new, as he hasn't maintained an ERA below 6.00 at any level since 2021. He has a knack for striking batters out at an above-average rate, but Kowar still holds virtually no fantasy value. Max Castillo was optioned to Omaha in a corresponding move.
