Each is a nominee. Baker's freshman hit "The Mentalist" earned him a nomination for best actor in a drama. Sutherland won that award in 2006, and is nominated this year for his role in a special "24" movie. Fey is up for best actress in a comedy, the award she won last year.
The live telecast is scheduled for 8 p.m. Eastern Time on Sunday.
The academy says other presenters include Jon Hamm of "Mad Men" and the "Gossip Girl" twosome of Blake Lively and Leighton Meester.
Also taking the stage to hand out trophies will be Alyson Hannigan and Jason Segel of "How I Met Your Mother," Stephen Moyer of "True Blood," NBC late-night host Jimmy Fallon, Dana Delany of "Desperate Housewives" and Chandra Wilson of "Grey's Anatomy," the academy said Monday.
