Kyra Sedgwick's hit cop drama, The Closer, has been renewed for a second season, the cable TV network TNT said Wednesday.

The series premiered on June 13 to an audience of more than 5.3 million households, making it ad-supported cable's top original scripted series telecast ever, and it has been renewed for a second 15-episode season.

The announcement was made by Steve Koonin, executive vice president and chief operating officer for TNT and sister network TBS.

The drama stars two-time Golden Globe-nominee Sedgwick as a tough, yet feminine, CIA-trained, Atlanta detective transferred to Los Angeles to head the Priority Homicide Division, much to the dismay of the mostly male department already in place.

With 'The Closer,' we've found a show that not only fits our brand and our current programming line-up perfectly, but also has proven to be one of television's biggest success stories of the summer, said Koonin.
