Williamson (hamstring) has resumed baseball activities, Marc Topkin of the Tampa Bay Times reports.
Out since early August with a right hamstring strain, Williamson will work out with the Rays through the weekend and could then begin a rehab assignment with Triple-A Durham next week. If Williamson is able to rejoin the Rays' active roster later this month, he could be used in a short-side platoon role at second base with Richie Palacios.
