Williamson is out of the lineup for Sunday's game against the Cardinals.
The 25-year-old was part of the Opening Day lineup against lefty Matthew Liberatore, but he's been held out of the starting nine for two straight games versus right-handers. Williamson will handle the short side of a platoon at second base with Richie Palacios until the Rays get Gavin Lux (shoulder) back from the injured list.
