Vince Friese took the 450SX main event holeshot over all of the past champions and whole slew of other solid riders. Friese was able to hold on to the lead for a half lap before Villopoto made a pass on him following the split lane section. Chad Reed, Justin Brayton, Ryan Dungey, Wil Hahn, James Stewart and Justin Barcia were all also able to advance past Friese as the field fought for positions in the opening laps. Out of the top-ten riders, Stewart did the most work in the first half of the race. He made rather quick work of Hahn before setting his sites on Dungey. Stewart was all over Dungey for a half lap before making the pass into fourth. Villopoto and Reed had opened up a comfortable gap by this point.
Stewart then took on Brayton for third. He made the block pass on Brayton, which opened up the door for Dungey as well. Dungey got Brayton just a couple corners later. Reed’s comfortable gap over third place quickly diminished when Stewart began to do a quad in the rhythm section following the start straight. Dungey followed suit and started doing the quad as well, but had to stretch it out and would come up short every now and then. After closing the gap on Reed through multiple laps, Stewart put the pass on Reed for second place just a couple corners after the quad. Dungey closed up on Reed as well, but was unable to get close enough to make a move for the last spot on the podium. Villopoto continued to ride away unchallenged for his second win of the season, followed by Stewart in second and Reed in third.
In the 250SX main event, Dean Wilson fired out of the gate first , but his Monster Energy/Pro Circuit Kawasaki teammate Justin Hill made an inside pass for the lead in the following corner. Jason Anderson had a decent start and was able to move quickly through the pack and up to second place in the opening laps. Red-plate holder Cole Seely battled with Osborne for fourth while the top three riders began to separate themselves from the rest of the field.
Anderson put his flat-track skills to use to put a pass on Hill through the inside of the start-straight corner for the lead, but that pass only lasted for one lane. Hill was set up for the inside line going into the following corner and rode Anderson high to retake the lead, also allowing Wilson to move into second. Wilson then overtook Hill with a block pass in the corner following the whoops. Anderson passed Hill back in the same corner Hill block passed him one lap earlier to take back second. Wilson had quite a gap over Anderson with five laps to go, but Anderson was able to whittle away at the gap through lapped traffic. As Anderson neared Wilson, Wilson suddenly and unexpectedly rolled the first triple on the track and in turn handed the lead over to Anderson. It was too late for Wilson to make a late-race charge and Anderson went on to take his third win of the season. Wilson took second and Hill took third for his first podium appearance. Wilson later stated on the podium that his bike died and caused him to roll the triple.
