We show that the pool rotation advances the transition of the cavity type - from deep seal to surface seal - marked by a reduction in the transitional Froude number. The role of the dimensionless rotational number $\\mathcal{S} \\equiv \\omega R_0/U_0$ on the transient cavity dynamics is unveiled, where $R_0$ is the sphere radius, $\\omega$ the angular speed of the liquid, and $U_0$ the impact velocity.
