LOS ANGELES -- With broadcast networks keeping their schedules free of scripted programming during the summer, cable has managed to make a substantial foothold.

Now, cable series "Burn Notice" and "Saving Grace" have reason to celebrate, as both have been picked up for second seasons with a 13 and 15-episode order, respectively.

USA's "Burn Notice" stars Jeffrey Donovan as a freelance spy who suddenly finds himself blacklisted and must return home to Miami while he tries to clear his name. It premiered in June to 4 million viewers and has been gradually growing its audience since then.

Helped out by a strong lead-in from "The Closer," TNT's "Saving Grace" had 6.4 million viewers for its premiere last month. Unlike "Burn Notice," it's audience hasn't grown, but is still averaging a respectable 5.5 million viewers each week.

Holly Hunter stars as Grace, a secular police detective who suddenly finds herself the beneficiary of some divine intervention.
