Fast National ratings for Friday, September 27, 2013.
 
ABC's "Shark Tank" was up from its early premiere and delivered Friday's top numbers among adults 18-49, but "Blue Bloods" returned above last year's premiere and combined with the transplanted "Hawaii Five-0" to give CBS the Friday win in the key measures.
 
FOX got good numbers from the premiere of "MasterChef: Junior," which won its hour in most young demos and easily outdistanced Friday performances from a different Gordon Ramsay show, "Kitchen Nightmares," in the same demo.
 
Those are the Friday positives, but it wouldn't be Friday without some low ratings as well. ABC's "Last Man Standing" dropped in its second week and combined with dismal second week numbers for "The Neighbors" to make the "Shark Tank" rise seem even more impressive.
 
On to the numbers…
