Mia Maestro is ready to strain herself for another season…

FX has given its new vampire drama The Strain, starring the 36-year-old Argentine actress and singer-songwriter, a long-expected 13-episode order for a second season to air in 2015.

The announcement comes only six weeks into The Strain’s 13-episode freshman run.

Maestro portrays Dr. Nora Martinez on the series from Mexican filmmaker Guillermo del Toro and Carlton Cuse.

The Strain, the first FX original series to air on Sunday night, tells the story of Dr. Ephraim Goodweather, the head of the Center for Disease Control Canary Team in New York City. He and his team are called upon to investigate a mysterious viral outbreak with hallmarks of an ancient and evil strain of vampirism. As the strain spreads, Eph, his team, and an assembly of everyday New Yorkers, wage war for the fate of humanity itself.

The series’ premiere drew 4.73 million total viewers and 2.43 million adults 18-49 in Live+Same Day. With Live+7 data, VOD, digital and electronic purchases, that number tripled to 12.7 million viewers to become the network’s highest-rated series premiere ever. The horror drama also ranks as the No. 1 new series on cable (broadcast or premium) in 2014 in delivery of adults 18-49.

“We’ve never had any doubts about The Strain,” said FX CEO John Landgraf. “Working with Guillermo del Toro, Carlton Cuse, and the brilliant cast led by Corey Stoll has been everything we had hoped it would be and more.”

On a weekly basis, The Strain, from FX Productions, is averaging 11 million total viewers and 5.2 million adults 18-49 inclusive of VOD and online viewing (most current).

On a first-run-only Live+7 basis, the series is averaging 4.5 million total viewers and 2.6 million adults 18-49. The Strain’s 1.2 million adults 18-34 (first-run L+7) places it in a tie for the top spot in that demo among all new cable series to launch in 2014.
