UPDATED TV ratings: Fontana, Sonoma

IndyCar's contentious MAVTV 500 at Fontana's Auto Club Speedway Saturday afternoon on NBCSN secured a 0.37 rating, according to ShowBuzzDaily, which is the same as for for the previous oval IndyCar round at Texas. It's also up from a 0.18 rating in 2014 when the race was run at night – and consequently suffered in TV audience due to an extremely late start time for the East Coast. The average audience was given as 512,000, which is the highest of the six races aired to date this season on NBCSN (the Texas race averaged 431,000).
