Maybe one of the most interesting battles of the night was in the second 450 semi, between Vince Friese (Smartop MotoConcepts Racing), Tommy Hahn (CycleTrader.com/Rock River/Yamaha), and Wil Hahn (Monster Energy Kawasaki). All three made it through, but not without some contact. It was interesting to watch the brothers working together during the race, with Tommy directing traffic.
