The Royals promoted Kudrna from Single-A Columbia to High-A Quad Cities on Wednesday.
Though Kudrna's numbers at Columbia this season (3.50 ERA, 1.40 WHIP, 66:26 K:BB in 64.1 innings) don't vary wildly from his ratios in 2022 with the same affiliate (3.61 ERA, 1.37 WHIP, 61:32 K:BB in 72.1 innings), the Royals evidently saw enough growth from the 20-year-old right-hander to bump him up a level. He's the second major Royals pitching prospect to move from Single-A to High-A within the past two weeks, as Frank Mozzicato got the call to Quad Cities on July 2.
