In the 450cc Main Event, fast-qualifier Dungey got a slow start. Stewart led the way, with Hill second and Dungey's teammate, Austin Stroupe, third. Villopoto, meanwhile, was buried mid-pack. With 14 of 20 laps remaining, Dungey appeared to be losing ground on Hill and Stewart, with Short closing fast in fourth. Ten laps later, though, the Minnesota native had not only passed both Hill and Stewart, he had opened up a comfortable lead, which he maintained to the checkers.
