USA Network is showing comedy creators that it is willing to stick with new series while they find their legs, giving a 13-episode second-season order to freshman paramedic comedy Sirens, from Fox TV Studios, Denis Leary and Bob Fisher. Sirens was the first original half-hour comedy series to launch under USA’s current push in the genre. It was a slow build but the show developed a following from a loyal core audience and even showed ratings growth over its run, despite losing its Suits lead-in halfway through. It ranks as the top new basic cable comedy series of the year among total viewers, averaging 1.62 million, and in adults 25-54 (870,000). “Sirens resonated with a broad fan base, and we are excited to grow this new audience further, as season two promises a lot more laughs and irreverent humor,” said USA Network President Chris McCumber. “We’re pleased to continue our partnership with Denis Leary and Bob Fisher, whose unique brand of witty, off-kilter and laugh-out-loud writing is brought to life by the immensely talented cast.”

The series stars Michael Mosley, Kevin Daniels, Kevin Bigley, Jessica McNamee and Josh Segarra and follows a group of Chicago’s best EMTs who are rock stars professionally, but struggle to keep their personal lives in order. Leary and Fisher exec produce alongside Jim Serpico, Hal Vogel, David Aukin and David Leach. USA’s second original comedy series, Playing House, is still airing. The network recently gave a second-season pickup to its breakout reality comedy series Chrisley Knows Best.
