As expected and following his win on Saturday, Rockstar Makita Yoshimura Suzuki's Mat Mladin, took victory number 66 on Sunday at Barber Motorsports Park.

The Australian swooped into the lead on the race's opening corner and that was pretty much the end of it.

His rival Ben Spies did apply some fairly heavy pressure for the opening handful of laps, but Mladin cracked open a gap on lap 4 of 28 and steadily built it from there, ultimately taking the chequered flag with over eight seconds to spare despite Spies' presence.

Another difficult weekend for Quebec's Miguel DuHamel, who took eighth on his Honda.

Mladin has now claimed every point available with two poles, three points for most laps led, and three consecutive wins. He will look to continue his perfect streak next weekend at Auto Club Speedway in Fontana, CA.
