Tampa Bay reinstated Williamson (hamstring) from the 10-day injured list Sunday.
Williamson has been out since Aug. 7 due to a hamstring strain. Before being sidelined, the 25-year-old was slashing .247/.309/.332 with three homers, 26 RBI and eight stolen bases in 270 plate appearances. The Rays designated Jake Fraley for assignment to make room for WIlliamson to rejoin the club.
