Last year’s freshman Showtime dramas Ray Donovan and Masters Of Sex will air as a block this summer, with their 12-episode second seasons set to premiere on Sunday, July 13. Last year, Ray Donovan launched in the summer behind the final season of Dexter, while Masters Of Sex unspooled in the fall behind Homeland. Showtime will likely use Homeland as a launching pad again this year for new drama series The Affair. Neither has been assigned a premiere date yet. Showtime’s next original scripted series premiere is thriller Penny Dreadful on May 11.
