Starring Angie Harmon and Sasha Alexander, the drama's second season debut was seen by 8.6 million viewers.
"This summer, 'Rizzoli & Isles' has proven that last year's record-breaking ratings were just the beginning of this show's remarkable track record," Michael Wright, executive vice president and head of programming for TNT, TBS and TCM, said in a statement. "With a terrific cast, a top-notch production team and the kind of stories TNT fans crave, 'Rizzoli & Isles' is poised to continue its success alongside blockbuster TNT series like 'The Closer' and 'Falling Skies.'"
The series is based on characters created by crime novelist Tess Gerritsen. Harmon plays Jane Rizzoli, a detective, and Alexander plays Maura Isles, a medical examiner.
