The white flag came out, and Voss was trying everything he could to get around. He made a charge through the whoops, but could not get by. In the next, and second to last, corner, Voss came together with Johnson and got around him. Johnson returned the favor in the next - the final - corner by riding into Voss, but Voss kept it on two wheels and held the position and a trip to the main. The riders shook hands after the aggressive battle. The fans cheered them both as they headed back to the pits - Voss to quickly prepare for the main, Johnson to pack it up for the weekend.
The lites main started with a big tangle going into the first turn. Far ahead of the problems, Josh Grant grabbed the holeshot and got immediately to work putting distance between himself and Steve Boniface, Ben Townley, Jake Weimer, and Tommy Hahn. Weimer went to work immediately on Boniface, and got by him right after they passed the green flag on the opening lap.
Chris Gosselaar, not one of the riders in the first turn pile up, did manage to crash at the beginning of the race and was never in contention.
Tommy Hahn was the man on the move and on lap seven of the twenty lap main he flew past Townley in the whoops to take over fourth place. Next Hahn went to work reeling in Boniface. On lap nine he was right behind Boniface as the two riders came up on a downed rider. Hahn passed, but allowed Boniface back by so he wouldn't pass under the yellow flags. He wasn't so kind in the very next corner, where he simply re-passed Boniface and this time kept the position.
Hahn looked like he was gaining on Weimer for a bit, but by the fifteenth lap it was clear Weimer had Hahn's pace covered. If anything, Weimer pulled the gap between them a little wider.
Grant was riding loose and relaxed out front, and the race was mostly uneventful through the final laps. The all-Honda podium was Grant with a huge lead, then Weimer, and then Hahn.
The Las Vegas Open saved the best race for last, and the supercross main was a thriller. Ivan Tedesco jumped into the lead by grabbing the holeshot, with David Vuillemin, James Stewart, Ricky Carmichael, and Kevin Windham right on his tail. Stewart made a try for second on Vuillemin just before starting the third lap, but Vuillemin held him back. Vuillemin had other plans. On that third lap, Vuillemin blitzed through the whoops and got past Tedesco to take over the lead. Tedesco almost went down from the contact pass, but stayed up to hold onto second.
On lap four, while still in second, Tedesco fell on a small double. Carmichael was able to capitalize as he and Stewart rode around Tedesco, and Ricky took over the second place position. By then Vuillemin had a strong handle on first, but Ricky, who'd set the fastest times in qualifying, started to cut into that lead.
By lap six Carmichael had a little breathing room on Stewart, and was slowly closing the gap on Vuillemin. By now the top three were pulling away from Windham, Byrne, Ferry, and Voss.
