On a night when the season premiere of ESPN’s “Monday Night Football” was expected to dominate in the final nationals, it was ABC and its three-hour finale of “Bachelor Pad” that led the broadcast pack Monday.

According to preliminary, affiliate-based national estimates from Nielsen, “Bachelor Pad” averaged a 2.3 rating/6 share in adults 18-49 and 7.1 million viewers overall, though these numbers could come down some in the nationals due to a preemption in New England for Patriots football. This preliminary score reps a roughly 20% week-to-week gain, and the show finished its second-season run ahead of last year’s averages.

Fox’s “Hell’s Kitchen” was the night’s top-rated broadcast show among young adults (2.4/6 in 18-49, 5.8 million viewers overall), though it was down week to week — likely the result of the tough football competition for male viewers. “Kitchen” cooks up its finale next Monday opposite the season and series premieres on other nets.

NBC was above its recent Monday average from 9 to 11 p.m. with the “Miss Universe Pageant” (1.6/4 in 18-49, 5.2 million viewers overall), though it came in down about 15% from last year’s August telecast and is believed to be a record low for the annual event. Opening the night, the net aired a repeat of “America’s Got Talent” (1.1/3 in 18-49, 4.4 million viewers overall).

CBS programs started late in most of the country due to an overrun of the U.S. Open tennis men’s final. Ratings are approximate for the rest of the night, with “How I Met Your Mother” airing its two repeat episodes at 8:30 p.m. (1.2/3 in 18-49, 3.5 million viewers overall) and 9 p.m. (1.3/3 in 18-49, 4.3 million viewers overall), followed by encores of “Two and a Half Men” (1.2/3 in 18-49, 4.2 million viewers overall), “Mike & Molly” (1.1/3 in 18-49, 4.5 million viewers overall) and “Hawaii Five-0” (1.0/3 in 18-49, 4.0 million viewers overall).

Ratings will be available this afternoon for ESPN’s “Monday Night Football” doubleheader featuring the New England Patriots against the Miami Dolphins in the opener and the Oakland Raiders against the Denver Broncos in the second matchup.

Preliminary 18-49 averages for the night: ABC, 2.3/6; Fox, 1.8/5; Univision, 1.7/4; NBC, 1.4/4; CBS, 1.2/3; CW, 0.5/1.

In total viewers: ABC, 7.1 million; NBC, 4.9 million; Fox, 4.6 million; CBS, 4.2 million; Univision, 3.7 million; CW, 1.2 million.
