Mcadoo led wire-to-wire for the race win with Jayce Pennington second and Dylan Walsh third. Mcadoo's 7-1 scores eluded him to the overall win. Tennant took the runner up position (2-6) and Garrett Marchbanks rounded out the podium (6-4).
"Tonight I was able to grab two strong starts and it paid off," said Mcadoo. "I had a similar downhill start setup that I practiced during the week. I'm stoked to walk away with a Toyota truck and the overall win tonight."
Reed powered his way to the to the Toyota holeshot in the third and final Monster Energy Cup Class Main Event of the night, while Alessi, Roczen, Seely and Musquin gave chase. Alessi gained control of the race early and Reed made a critical mistake on the opening lap that saw him hit the deck and move Dungey into the top five. Tomac was buried in the pack and circulated the opening lap in 10thplace.
Alessi rode brilliantly as he clicked off lap-after-lap, opening a small lead as the competition swapped positions behind him. Roczen began to slowly chip away at Alessi's lead and eventually made the pass for the lead on Lap 4. Musquin bumped his way into second, followed by Dungey just one lap later. Tomac was on a mission as he carved his way through the talented field and moved into fourth on Lap 6.
As Roczen continued to lead, the battle for the overall win was shaping up to go down to the wire between Dungey and Tomac. On Lap 7, a slight bobble by Dungey allowed Tomac to jump to the inside and make the pass for third. Roczen and Musquin elected to take the joker lane on the ninth lap, while Dungey and Tomac waited until the final lap. Dungey was hot on Tomac's heels and made the pass towards the end of the final lap to retake third.
Roczen impressively rebounded from his crash earlier in the night to cross the checkered flag for his second race win of the night. Musquin took second, just ahead of Dungey, Tomac and Alessi, who rounded out the top five.
Tomac edged Dungey out by one point for the overall win (2-1-4) on the night. Dungey was second (3-2-3) and Musquin third (4-3-2).
"It was a crazy race and I did not make it easy on myself with a terrible start," said Tomac. "I knew going into the race that I just needed to finish behind Ryan [Dungey] and I was able to catch up to him and have a good battle before settling on the last lap. I'm really happy with tonight's performance and looking forward to the next season."
The best Freestyle Motocross Riders from around the world made a special appearance as they competed in several high-flying competitions throughout the day. Despite strong winds, the athletes put it all on the line and Taka Higashino used a backflip lazy boy to emerge as the winner in the FMX High Rollers Contest. Jared McNeil led the way in FMX QuarterPipe Big Air, while Tom Parson took the top honors in the Dirt Shark Best Whip contest.
