Before 49,082 fans at the inaugural Monster Energy AMA Supercross, an FIM World Championship, at Cowboys Stadium, Rockstar Makita Suzukis Ryan Dungey, of Belle Plaine, Minn., won his fourth AMA supercross class main event. Rockstar Suzukis Blake Bagget, of Grand Terrace, Calif., won the Eastern Regional AMA Supercross Lites class main event, marking the first win of his career.

Ti-Lube/Babbits/MSR/Formost/Kawasakis Nick Wey opened the AMA Supercross class main event by winning the Spike Holeshot. Dungey quickly passed Wey for the lead. After the first lap San Manuel Yamahas Josh Hill, of Yoncalla, Ore., and Honda Red Bull Racings Davi Millsaps, trailed Dungey in second and third respectively.

Millsaps made his way around Hill on lap four to secure second place as Dungey extended his lead out front. Millsaps Honda Red Bull Racing teammate Trey Canard made the pass for third place on lap nine. Canard spent the rest of the race stalking Millsaps for the next 11 laps but was unable to make the pass. Dungey held on for the win, Millsaps finished second and Canard finished third.

This was a big win for me tonight, but there are still a lot of races left to go, said Dungey. The track got really rough tonight, so that kept me on my toes. I am looking forward to going to Jacksonville next weekend.

After nearly the entire field went down in turn one of the Eastern Regional AMA Supercross Lites class, Ryan Sipes, of Vine Grove, Ken., won the Spike Holeshot Award. Points leader Christophe Pourcel, of Groveland, Fla., remounted in last place. At the end of lap one, Sipes led BTO Sports.com/BBMX/Palmetto Suzukis Troy Adams, of Homosassa, Fla., and Rockstar Suzukis Jake Moss, of Temecula, Calif., who followed in second and third respectively.

On the second lap, Adams and Moss collided, causing both of them to withdraw from the race. Bagget moved into second place following the crash and set his sights on Sipes. On lap 14, Bagget, a rookie this year, moved past Sipes and rode to victory. Sipes finished second and GEICO Powersports Hondas Justin Barcia, Ochlocknee, Ga., finished third.

This is a dream come true, said Bagget with tears of joy running down his face. I was following Ryan (Sipes) and he didnt make any mistakes, so I had to be patient. Time was starting to run out and I dove inside and made the pass for the win.

Pourcel finished seventh and still holds a five point lead in the Eastern Regional AMA Supercross Lites class championship.
