"Off the Map," the ABC medical drama shot in Hawaii, posted strong viewer numbers in its target audience Wednesday night even though it finished behind the major network offerings in the hour, according to Nielsen ratings info released by ABC Thursday. 

In its third episode, "Off the Map" drew 5.1 million viewers. The mid-season replacement airs at 9 p.m. Wednesdays on KITV. 

The CBS drama "Blue Bloods" won the hour by attracting 12.1 million viewers. NBC’s "Law & Order SVU" finished second but its 5.5 million viewers gave it a slim lead over "Off the Map."

But among adults 18-49, the ABC show finished second by attracting 1.8 percent of the total TV viewing audience and 5 percent of those who were watching TV at the time.
