It was an East Coast vs. West Coast battle on the season finale of MasterChef Jr. (1.5/5) last night. After a 7-episode run, NYC’s 13-year old Alexander Weiss and Culver City’s 12-year old Dara Yu faced off for the trophy and the $100,000 grand prize. For Fox, the latest Gordon Ramsay show has proven a winner too. A solid Friday night ratings return since its September 27 debut, MasterChef Jr was up 15% among adults 18-49 last night and bopped up 5% among total viewers to 4.2 million. All of which gave the freshman its best demo and viewership results since its premiere. While not officially renewed for a second season yet, MasterChef Jr. looks to be a sure bet to back on the network that seemingly can’t get enough Ramsay. Additionally Ramsay beat Ramsay as MC Jr.’s finale brought the network a 25% jump over the same night last year when Kitchen Nightmares pulled in a 1.2/4 on November 9, 2012. With a Sleepy Hollow (0.6/2) encore ending its night, Fox got a 1.0/3 rating Friday.

In terms of who won the night in the key demo on Friday, it was a 1.5.5 ratings tie between ABC and CBS. The latter came in first in total viewers with 9.89 million viewers to the former’s 6.197 million.

Once again, Shark Tank (2.0/6) was the highest rated show of the night for the 8th week in a row. Last night’s telecast of the entrepreneurial reality series was even with last week’s show to match a season high. Shark Tank has hit that 2.0 four times this season so there is a good chance, based on its usual one-tenth rise from nationals to final numbers precedent, that it could hit a new demo high when the numbers come in later today. The No. 2 spot in the 9 PM slot saw a reversal of fortune. For the first time this season CBS’ Hawaii Five-O (1.4/5) topped NBC’s Grimm (1.3/4) in the demo. The 50th state-set cop drama was up 8% from its November 1 show while in the third week of its third season, the procedural fantasy show was down again – this time 15% from last week to a season low. Of course, this is just round 1 and Grimm is a big DVR gainer that could catch up with Five-O when the Live+3 numbers come in next week. In terms of viewership, Five-O was down a small bit from last week to 9.39 million watching while Grimm remained basically steady at 4.94 million.

Elsewhere last night, NBC’s Dateline (1.0/4) at 8PM was down three-tenths from its last original but up 43% over last week’s limp Why We (Heart) Vampires special that the network ran in the slot. Talking about vampires, Dracula (1.0/3) did not find any fresh blood at 10 PM last night. The new series saw a biting 23% drop in its third week The Jonathan Rhys Meyers starrer also was down in viewers from last week’s 3.4 million watching to 2.99 million last night.

On CBS, Undercover Boss (1.8/6) started network primetime and provided a strong lead-in to Five-O as the reality show surged up 29% from last week. With 10.98 million viewers at 10 PM, Blue Bloods (1.3/4) was the most watched show of the night once again and up from last week’s 10.7 million. Among the demo, the Tom Selleck-led family cop drama saw an 8% rise over its November 1 show. ABC’s comedies Last Man Standing (1.4/5) and The Neighbors (1.0/4) were respectively steady and up 10% in the demo. While winning its 10 PM time slot over Blue Bloods (8%) and Dracula (40%), News mag 20/20 (1.4/5) was down a tenth from last week in the demo and down in viewership to 6.0 million from last week’s season high of 7.65 million.

The CW saw both The Carrie Diaries (0.3/1) and America’s Next Top Model (0.4/1) even with their results of last week.
