Scott Dixon is having one of those near-perfect seasons, and it’s more than a little frustrating for the guy trying to chase him down. Dixon came from behind Saturday night at Kentucky Speedway, passing Helio Castroneves coming off the final turn on the 1.5-mile oval to win the Meijer Indy 300. It was the second win in a row and the sixth victory of the season for Dixon, tying the record of Chip Ganassi Racing teammate Dan Wheldon as he races toward what would be his second IndyCar Series championship. Series runner-up Castroneves, still trying for his first victory of the season and his first series title as he chases Dixon, tried to get this one with fuel strategy.
