Navi Rawat, who's already filmed one pilot this spring, has taken a role in another.

The actress, currently in a recurring role on "The O.C.," will co-star in the CBS drama pilot "Numbers," according to The Hollywood Reporter. William Devane, Kristin Bauer, Melissa De Sousa and Jarrad Paul have also joined pilots.

In "Numbers," Rawat will play an MIT classmate of star David Krumholtz, a mathematician enlisted by the FBI to help solve crimes. Her role there would come second to FOX's drama "North Shore," which she's already filmed.

Given that FOX placed a 13-episode order for "North Shore" earlier this week, something will likely have to give.

Devane ("Knots Landing," "The Michael Richards Show") will star in ABC's untitled Staley/Long comedy. He'll play a man who reconnects with his estranged son (Tom Everett Scott) when both become fathers at the same time.

Also at ABC, Paul ("Action," "UC: Undercover") has joined the cast of the private-eye drama "Harry Green and Eugene," Anne Dudek ("For the People") has signed on to the untitled Lewis Black/high school comedy, and John Francis Daley ("Freaks and Geeks") will play Marissa Jaret Winokur's brother in the comedy "The Furst Family."

Bauer ("Hidden Hills") has joined The WB's comedy "Commando Nanny," from producer Mark Burnett. She'll play the mother of three kids cared for by a former British soldier-turned-nanny. Elsewhere at the network, Branden Williams ("Never Been Kissed") has signed on to the comedy "Shacking Up" (formerly "Robbing the Cradle").

Elsewhere, De Sousa ("One on One") has been cast in UPN's comedy "Second Time Around," Kaitlin Olson ("Meet the Marks," "Curb Your Enthusiasm") will be part of "The Sketch Show" for FOX, and Troy Winbush ("The Cosby Show," "John Q") has joined NBC's untitled medical mystery drama.
