UPDATE: Last Sunday's NASCAR Cup Series playoff race at Las Vegas earned a 1.3 rating and 2.14 million viewers on NBCSN - down a tick in ratings and 7% in viewership from last year's playoff opener on the same weekend (Chicagoland: 1.4, 2.31M).
Compared to the race it replaced on the schedule, New Hampshire, ratings were flat and viewership increased 7% from 1.99 million.
Las Vegas was the 14th Cup Series race with less than a 2.0 rating this year, surpassing last year's full-season total of 12. Again, that excludes rainouts. It was the fifth race with less than a 1.5 rating, exceeding the previous 17 seasons combined (four).
