Dungey went into the Main Event with a convincing Heat 2 win and the fastest lap in practice. With a few tweaks on his suspension to fine-tune his RM-Z450, he lined up on the starting gate looking to extend his lead in the Supercross class: He has won four rounds so far in 2010 and he looked confident in his ability to race well on the dirt in Reliant Stadium. After the first corner, Dungey found himself in third place. He and his bike worked hard to overcome the deep whoops and traded spots with a few racers throughout the first half of the race. At the midway point, just as he was about to catch and pass the third place rider, Dungey stalled his bike in a complicated turn. Stuck in the whooped-out corner as a few racers passed him, Dungey managed to restart his bike and move himself into fifth place where he finished the race. "Some tracks favour you more than others, and some tracks you have to adapt to when things aren't working," Dungey said after the race. "I stalled it in the middle of the race, but overall I'm all right with tonight. We'll get out of here still holding onto the lead and I'll learn from tonight and move on."
