Though down from last year’s especially strong showing, the final night of ABC’s “The Bachelor” dominated Monday’s primetime ratings race. Fox’s “House” was the evening’s top scripted program as the net ran second.

According to preliminary nationals from Nielsen, the two-hour finale of “The Bachelor” averaged a strong 4.5 rating/12 share in adults 18-49 and 13.8 million viewers overall — down 15% from last spring’s finale but up 45% from last week’s penultimate episode; and in total viewers, this repped the show’s third most-watched finale in its last 11 seasons. It was followed by the 10 p.m. special “The Bachelor: After the Final Rose” (4.7/12 in 18-49, 13.9 million viewers overall) as ABC dominated the night, carrying each half-hour and winning by 4 shares in adults 18-49 over runner-up Fox.

At Fox, “House” (3.5/10 in 18-49, 10.3 million viewers overall) was down 8% week to week (likely due to the start of Daylight Saving Time) but was the night’s No. 1 program in 18-49 as well as key male demos. And at 9, “The Chicago Code” (1.9/5 in 18-49, 7.3 million viewers overall) was down a tick week to week and ran third for its 9 o’clock hour in most categories.

CBS saw new comedy “Mad Love” hit a low at 8:30 (2.1/6 in 18-49, 6.5 million viewers overall), building slightly on its lead-in from a repeat “How I Met Your Mother” (1.9/6 in 18-49, 6.1 million viewers overall). Also down opposite the strong ABC competition were repeats of “Two and a Half Men” (2.6/7 in 18-49, 9.8 million viewers overall) and “Mike & Molly” (2.2/6 in 18-49, 8.5 million viewers overall), while 10 p.m. drama “Hawaii Five-0” dipped a bit less (1.9/5 in 18-49, 7.3 million viewers overall) to remain second among the broadcasters in 18-49.

At NBC, which was edged out in adults 18-49 on the night by Univision, “Chuck” (1.6/5 in 18-49, 5.0 million viewers overall) and “The Event” (1.2/3 in 18-49, 4.2 million viewers overall) hit lows, while 10 p.m. drama “Harry’s Law” (1.7/5 in 18-49, 10.0 million viewers overall) continues to be something of a bright spot. The Kathy Bates-led drama again built on its lead-in while drawing its largest overall audience in six weeks.

CW aired repeats of “90210” (0.3/1 in 18-49, 0.7 million viewers overall) and “One Tree Hill” (0.2/1 in 18-49, 0.5 million viewers overall), both of which won’t return with originals until April 18.

Preliminary 18-49 averages for the night: ABC, 4.5/12; Fox, 2.7/8; CBS, 2.1/6; Univision, 1.6/4; NBC, 1.5/4; CW, 0.3/1.

In total viewers: ABC, 13.8 million; Fox, 8.8 million; CBS, 7.6 million; NBC, 6.4 million; Univision, 4.1 million; CW, 0.6 million.
