It was more of the same but with a little bit more where it counted for several originals on the Big 4 last night as NBC and Fox finished in a dead heat in the key demo. With a 1.2/5 each among adults 18-49, the both nets saw a pretty good Wednesday amid the last days of summer.

Part of that for Fox was that things heated up on MasterChef with its Mexican Tag Team Challenge and more. The Gordon Ramsay-hosted cooking competition series saw double-digit demo rises for both its 8 PM and 9 PM airings last night: with a 1.1/5, MasterChef was up 10% in the first hour compared with its August 23 show and, with a 1.3/5 in the second hour, rose 18% over last week. Add that all up and Fox was up a tenth over August 23.

Of course, with top dog America’s Got Talent (2.0/9) in its corner, NBC was way ahead of Fox in viewership. Pumped by AGT’s 11.07 million sets of eyeballs, up 2% from last week, the net pulled in 5.70 million to Fox’s 3.68 million. AGT was flat in the demo.

However, the real happy dance at 30 Rock and up at Universal may be from the results of the third week of Marlon. With a 1.0/4, the 9:30 PM episode of the new sitcom held its entire demo from last week. But, scoring a 1.2/5, the 9 PM broadcast was up almost 10% from August 23, not to mention an 11% viewership bump to 5.1 million. It currently makes Marlon‘s Week 3 the most watched new summer comedy in 13 years.

CBS’ Big Brother (1.8/7) matched its final numbers of last week in the demo and saw a 1% viewership rise to 6.18 million. Perhaps, warranting a happy jig or not at the House of Moonves, the struggling Salvation (0.5/2) is currently up 25% from last week’s final numbers. However, it is also currently even with last week’s fast affiliates, which were adjusted down a tenth.

ABC’s only original of the night was a special 20/20 (0.7/3) focusing on the devastation of Hurricane Harvey in Houston (stay strong, Lone Star State). The CW aired two episodes of its CW Seed series Vixen from 8-10 PM, with the animated show getting a 0.2/1 in both hours.
