McGarrett and crew not only nabbed the murderous ninja triathletes in last night’s episode of “Hawaii Five-0” but for the second week in a row they also captured the hour, according to Nielsen ratings released by CBS. 

The crime drama drew 12.34 million viewers, its largest audience since Sept. 27. 

ABC’s “Skating With Stars,” which aired instead of “Castle,” drew 6.91 million viewers. Over on NBC, “Chase” drew 5.34 million viewers.

“Hawaii Five-0” airs in Hawaii at 9 p.m. Mondays on KGMB.
