Wisler (neck) will throw a bullpen session Saturday, Neil Solondz of the Rays Radio Network reports.
Wisler has been sidelined since July 27 and is ramping up his activity for the first time since landing on the injured list. If all goes well with his session Saturday, Wisler could throw live batting practice as early as Monday. It's unclear if he will require a rehab assignment, but a return in early September appears realistic.
