Holton and Lucas Braun were traded by Atlanta to Kansas City on Saturday in exchange for Lane Thomas and Bailey Falter, Robert Murray of FanSided.com reports.
Holton was a second-round selection of Atlanta in the 2024 First-Year Player Draft but will now look to work his way up the Royals' farm system. He's spent most of the 2026 season in Single-A, where has a 2-1 record over seven outings (six starts) with a 5.08 ERA, 1.39 WHIP and 30:13 K:BB over 33.2 innings.
