With an assist from college basketball, which bled about 15 minutes into primetime, CBS notched a Sunday ratings victory in key demos behind solid perfs from “The Amazing Race,” “Undercover Boss” and “CSI: Miami.”

The Eye’s primetime lineup started late in much of the country due to an NCAA men’s basketball tournament game running long, and the net opted to start all three of its entertainment series late following “60 Minutes” (roughly 2.0/7 in 18-49, 10.8 million viewers overall). Numbers for the net’s programs are subject to revision in the nationals on Tuesday, but “Amazing Race” (2.5/7 in 18-49, 10.6 million viewers overall), “Undercover Boss” (2.7/7 in 18-49, 10.9 million viewers overall) and “CSI: Miami” (2.7/8 in 18-49, 11.5 million viewers overall) all delivered similarly solid scores from 8 to 11.

Fox ran second in demos, led by “Family Guy” (3.4/9 in 18-49, 6.6 million viewers overall) — the No. 1 show of the night among young adults — and “The Cleveland Show” (2.7/7 in 18-49, 5.5 million viewers overall). Earlier, a repeat “The Simpsons” placed third in most categories at 8 o’clock (2.0/6 in 18-49, 4.7 million viewers overall), and an original “Bob’s Burgers” built a bit on “The Simpsons” at 8:30 (2.2/6 in 18-49, 4.4 million viewers overall).

NBC started slowly with “Dateline” (0.9/3 in 18-49, 5.3 million viewers overall) and “America’s Next Great Restaurant” (1.2/4 in 18-49, 3.9 million viewers overall) before spiking in the evening’s final two hours with “Celebrity Apprentice” (2.8/7 in 18-49, 8.0 million viewers overall), which was flat week to week and again led the 10 o’clock hour in key demos.

ABC opened with a repeat of “America’s Funniest Home Videos” (1.5/5 in 18-49, 6.8 million viewers overall), followed by an original “Secret Millionaire” (2.4/7 in 18-49, 10.2 million viewers overall), which declined a bit more in its third outing but is still looking pretty good and providing the net with time period gains vs. last year. The alternative series were followed by a special preview of Friday reality series “Shark Tank” (1.9/5 in 18-49, 6.2 million viewers overall), which kicks off its second season this week, and a special off-night season (and probably series) finale for struggling first-year Tuesday cop drama “Detroit 1-8-7” (1.1/3 in 18-49, 4.7 million viewers overall).

Preliminary 18-49 averages for the night: CBS, 2.5/7; Fox, 2.1/6; NBC, 1.9/6; ABC, 1.7/5; Univision, 0.9/3.

In total viewers: CBS, 10.9 million; ABC, 7.0 million; NBC, 6.3 million; Fox, 4.4 million; Univision, 2.3 million.
