Aya Sumika will go from recurring to regular for the CBS drama's upcoming season

With the exit of co-star Diane Farr, CBS' "Numb3rs" has now added two new female regulars for its upcoming fifth season.

Aya Sumika, who has had a recurring role on "Numb3rs" for the past two seasons, will be a regular this season, according to The Hollywood Reporter.

Sumika, who plays Special Agent Warner, sometime love interest for Rob Morrow's Don Eppes, will achieve regular status along with Sophina Brown. The "Shark" veteran was previously reported to be playing a new junior agent in the Los Angeles-based FBI team.

Other credits for Sumika include "Hawaii" and an episode of "The O.C."
