UPDATE: The NASCAR Cup Series playoffs from Phoenix earned a 2.0 rating and 3.31 million viewers on NBCSN, down 9% in ratings and viewership from last year (2.2, 3.64M) and down 17% and 18% respectively from 2016 (2.4, 4.03M).
Excluding rainouts, Kyle Busch's win ranks as the lowest rated edition of the race since at least 2000 and the least-watched since at least 2001. The previous lows were set last year.
In what constitutes a bright spot for NASCAR, Phoenix was just the seventh race this season to avoid a double-digit decline.
It also delivered the second-largest audience of the playoffs, behind Talladega (2.2, 3.51M), though that is not unusual for the second-to-last race of the season.
