The numbers are in for UFC on FOX 13 and the preliminary figures give the event 2.27 million viewers and an .9 in the coveted 18-49 demographic, according to TV By The Numbers.

Saturday's numbers are a jump up from the UFC on FOX 12 overnights, which only saw 2.02 million viewers and .8 in the 18-49 demographic.

UFC on FOX 13 was headlined by a heavyweight non-title bout between Stipe Miocic and Junior dos Santos. Santos and Miocic went the distance when the Brazilian claimed the unanimous decision win.

Most of the main event was not figured into the overnight rating, which only measures the 8-10 p.m. time slot for FOX in the Eastern time zone, the 7-9 p.m. slot in the Central time zone, and the 6-8 p.m. slot in the Mountain time zone.

The rating measures the 8-10 p.m. slot in the Pacific time zone, but the UFC aired from 5-7:30 p.m. so it measures the audience the local affiliates aired in that slot, which is why the first figure can often change significantly when the final numbers come in.

The final ratings number, which will be out on Monday or Tuesday, is expected to be higher given the West Coast viewership and the second through fifth round of the main event figured in.

UFC on FOX 13 took place at the U.S. Airways Arena in Phoenix, Arizona.
