The Rays activated Walls (hip) from the 60-day injured list Friday, Tricia Whitaker of Bally Sports Sun reports.
Walls has been out all season following offseason hip surgery and had his recovery delayed due to inflammation in the hip. However, he recently got back up to speed during a five-game rehab stint with Triple-A Durham, going 8-for-21 at the plate. Walls could take some playing time away from Jose Caballero at shortstop while working in a utility role.
