Overnight ratings dropped again for NASCAR’s Chase For the Cup, but Talladega scored the sport’s top overnight rating in over six weeks.

NASCAR Sprint Cup racing from Talladega, the sixth race in the Chase For the Cup, drew a 2.5 overnight rating on NBCSN Sunday afternoon — down 7% from last year and 2013, when coverage aired on ESPN (2.7 both years), and the 17th of 18 races on cable this year to have a decline in overnights.

Despite the decline, the 2.5 overnight is the highest for any NASCAR race since Darlington on Labor Day weekend, which aired on the NBC broadcast network (3.4). The previous mark over that span was a 2.2 for Kansas the week before, which also aired on NBC.

The 2.5 is also tied as the second-highest overnight for NASCAR on cable this season, matching Pocono in August and Martinsville on Fox Sports 1 in March. The only race to have a higher overnight on cable was the Brickyard 400, which drew a 2.9 on NBCSN in July.

Head-to-head, NASCAR on NBCSN more-than-tripled competing coverage of the Formula 1 U.S. Grand Prix on NBC (0.7).
