Ratings Chart Attack!

A special reunion episode of “Baby Borrowers” bumbled in the ratings, falling off from its summer average by more than half.

NBC’s “Borrowers” grasped a 1.2 rating/3 share in the 18- to 49-year-old demographic, according to preliminary Nielsen research. The show slipped 43% from last week and 52% from the show’s previous summer average.

NBC ended the night fourth with a 1.2/4.

Fox’s “So You Think You Can Dance” (3.0/10) is finishing its run, airing the first part of its season finale. “Dance” stayed flat from last week, but helped Fox handily beat second-place CBS by 76%. Fox led the night with a 3.0/10.

CBS’ time-slot shift of “Greatest American Dog” (1.5/5) isn’t causing anyone to sit up and beg, as the numbers remained the same from last week’s lackluster time-period premiere. Second-place CBS pulled in a 1.7/5.

ABC took third with a 1.4/5, with repeats and a special “Primetime: China Inside Out” (1.5/5).

The CW brought up the rear with a 0.4/1.
