Double-A Northwest Arkansas placed Zobac on the 7-day injured list April 2 with an undisclosed injury, Sam Dykstra of MLB Pipeline reports.
The Royals protected Zobac from the Rule 5 Draft despite the fact knee injuries limited him to 36.1 innings at Double-A in 2025. His above-average fastball and slider should eventually fit in the middle of a big-league bullpen, although he is still being developed as a starter entering his age-25 season.
