Coolbeth sat on the pole for the 25-lap main event, only to come off the line fourth. He threaded his way past Bryan Bigelow and round-six winner Jared Mees to run second to former series champion Joe Kopp. Coolbeth then appeared to be closing in on Kopp, setting up a battle for the lead, but that battle never materialized, as Kopp dropped out with mechanical troubles on lap 19. Coolbeth inherited the lead and held it to the finish.
Mees finished second, upping his podium streak to two, while reigning series champion Chris Carr put together a charge that took him past Rich King and into to third place.
With the win, Coolbeth became the sixth different winner in the seven rounds of the series run thus far. Only Carr has two wins, and Carr remains in the series points lead, with 121 points, although Coolbeth trails him by just 16. Mees, who is enjoying the best season of his still-young career, is third, with 90.
