A pair of new crime dramas, ABC’s “The Evidence” and NBC’s “Heist,” bowed to soft ratings Wednesday night, which was kinder to unscripted skeins “American Idol,” “Deal or No Deal” and Fox’s premiering “Unanimous.”

According to preliminary nationals from Nielsen, Fox easily captured the night behind the first half-hour results show of the season at 9 (11.3 rating/26 share in adults 18-49, 27.3 million viewers overall) and the bow of “Unanimous” at 9:30 (7.0/16 in 18-49, 15.8 million viewers overall). Latter held onto more of its “Idol” lead-in than any Fox premiering skein since “The Swan” two years ago.

Fox also looked pretty good at 8 with a second-place showing for drama “Bones” (4.0/11 in 18-49, 11.1 million viewers overall).

NBC started the night on a good note with a special “Deal or No Deal” (5.1/14 in 18-49, 14.8 million viewers overall) but fizzled at 9 with the timeslot debut of “Law & Order” (2.6/6 in 18-49, 9.0 million viewers overall), which ranked fourth with its lowest firstrun score to date. And at 10, “Heist” (3.0/8 in 18-49, 8.7 million viewers overall) placed third, although it did build a bit on its “Law” lead-in.

ABC ran third in the opening hour with “George Lopez” (2.8/8 in 18-49, 7.3 million viewers overall) and “Freddie” (3.3/8 in 18-49, 7.8 million viewers overall) before picking up at 9 with “Lost” (6.6/15 in 18-49, 16.0 million viewers overall), although the drama posted its lowest score for an original seg this season. “The Evidence” closed things out with a second-place finish at 10 (3.4/9 in 18-49, 9.2 million viewers overall) — but like former slot occupant “Invasion,” it lost a big chunk of its “Lost” lead-in and then lost share points in its second half-hour.

CBS struggled from 8 to 9 with the Wednesday premieres of transplanted Monday comedies “Out of Practice” (2.0/6 in 18-49, 7.1 million viewers overall) and “Courting Alex” (1.8/5 in 18-49, 6.5 million viewers overall). Net moved up to third at 9 with “Criminal Minds” (3.4/8 in 18-49, 11.9 million viewers overall) and led at 10 with “CSI: NY” (4.4/12 in 18-49, 13.9 million viewers overall).

UPN again scored with “America’s Next Top Model” (2.4/6 in 18-49, 5.2 million viewers overall), which was up week-to-week and led its time period among women 18-34.

Preliminary 18-49 averages for the night: Fox, 6.6/16; ABC, 4.4/11; CBS, 3.2/8; UPN, 1.8/4; WB, 0.9/2.

In total viewers: Fox, 16.3 million; ABC, 10.9 million; CBS, 10.9 million; NBC, 10.8 million; UPN, 3.9 million; WB, 0.9/2.
