The Royals selected Zobac's contract from Double-A Northwest Arkansas on Tuesday, Anne Rogers of MLB.com reports.
The right-hander missed time in 2025 due to a knee injury, which limited him to 14 appearances. Zobac spent most of the campaign with Northwest Arkansas and had a 7.68 ERA over 36.1 innings, but the Royals still elected to shield him from potentially being selected in the upcoming Rule 5 Draft.
