Williamson will start at shortstop and bat sixth in Sunday's game against the Guardians.
Williamson will stick in the starting nine for a fourth straight game while top shortstop Taylor Walls (fingers) is on the bench for another contest. If his hyperextended fingers don't force him to the injured list, Walls will eventually settle back in as the Rays' everyday shortstop, which will push Williamson back into the short side of a platoon at second base with Richie Palacios.
