The Rays placed Williamson on the 10-day injured list Friday, retroactive to Thursday, due to a right hamstring strain.
Williamson tweaked his hamstring during Wednesday's game against the Rockies, and the injury is severe enough for him to require a stint on the injured list. A minimum stint on the IL would have him on track to return around mid-August, but Rays manager Kevin Cash relayed Friday that Williamson is "going to be out for some time," with the team hopeful that the 25-year-old will return for the end of the regular season, per Marc Topkin of the Tampa Bay Times. Carson Williams was recalled from Triple-A Durham in a corresponding move to bolster the Rays' infield depth in Williamson's absence.
