The fifth season premiere of The League grew on Sunny, drawing 786,000 total viewers and 687,000 in the 18-49 demo. The show retained 94 percent of its viewers in the 18-49 demo from last season's launch.

"The numbers last night on FXX for Sunny and The League far exceeded our highest expectations," FX Networks CEO John Landgraf said in a statement.  "To have just launched the channel three days ago and get these ratings is thrilling.  The delivery of these shows needs no qualification, they are proven appointment viewing for young adult audiences. Thanks to the fans and congratulations to Rob McElhenney, Glenn Howerton, Charlie Day and everyone involved with Sunny, and to Jeff and Jackie Schaffer and everyone on The League."
