Wendell Pierce has joined the cast of Ray Donovan.

The veteran actor (The Wire, Treme) will come on board Season 2 of this Showtime drama as Mr. Keith, a parole officer who receives a payoff from Ray as part of his down-on-his-luck life.

Pierce recently concluded the fourth and final season of Treme, and also appeared on The Michael J. Fox Show.

Production on Ray Donovan Season 2 is underway, with Hank Azaria, along with actresses Sherilyn Fenn and Vinessa Shaw also set to play key role this fall.
