Rockstar Makita Suzuki’s Mike Alessi grabbed the Supercross holeshot with San Manuel Yamaha’s James Stewart right behind him. Alessi led about half of the opening lap before Stewart flew by. Alessi’s Rockstar/Makita Suzuki teammate Chad Reed worked his way into second desperately trying to catch Stewart, while Honda Red Bull Racing’s Ivan Tedesco grabbed third.
Stewart was smooth and continued to pull away from Reed, who continued to pull away from Tedesco. Meanwhile, Alessi was locked in a battle for fourth with DNA Energy/BTOSports.com/BBMX's Matt Boni. Honda Red Bull Racing's Andrew Short soon passed them both, though, and began to battle it out for third with Tedesco.
The rutted track made line choice extremely important, and both Reed and Stewart were essentially following the same lines, which meant Reed was having a hard time reeling in Stewart. By lap seven, the battle for third place involved the Josh Grant/Tedesco/Short/Broc Hepler foursome, who battled it out for several laps. As that battle dwindled down as riders fell or just made big mistakes, Josh Hill began working his way through, and eventually chased down Grant for third, where he would finish.
Stewart continued to increase his lead throughout the race, eventually taking an easy final lap and victory, while Reed hung on for second. Hill was third, Grant stayed in fourth, and Tedesco grabbed fifth. Jason Lawrence did not race due to a hand injury, despite qualifying for the main event successfully.
This win for Stewart moves him back to eight points behind Reed with four rounds remaining.
Division 7/Star Racing Yamaha’s Broc Tickle grabbed the Lites holeshot this week and proceeded to lead the first couple laps before Monster Energy/Pro Circuit Kawasaki’s Christophe Pourcel found his way past. Pourcel's teammate Austin Stroupe soon followed suit. While Pourcel was pulling farther ahead of Stroupe and Tickle, Tickle's Star Racing Yamaha teammate Matt Lemoine was in a battle of his own for fifth along with Rockstar/Makita Suzuki’s Nico Izzi and Suzuki City’s Matt Goerke, while Branden Jesseman ran a solitary fourth.
Wil Hahn added himself into the mix on lap 13, passing the fallen Izzi for sixth, and last week's winner Blake Wharton fell early in the race and fought his way all the way through the pack to tenth place this week.
However, Pourcel's win was enough to clinch his first-ever SX title with one round remaining, as he leads his teammate Stroupe by 28 points.
