Monster Energy/Pro Circuit/Kawasaki's Adam Cianciarulo grabbed his third consecutive overall victory in three rounds thus far in the 2019 Lucas Oil Pro Motocross Championship at Thunder Valley Motocross Park in Lakewood, Colorado. In moto 1, Cianciarulo came out of the first turn in second, keeping race leader Monster Energy/Yamalube/Star/Yamaha Racing's Justin Cooper in his sights until, with only six minutes remaining in the moto, the race was forced to be cut short due to lightning nearby, resulting in both the red and checkered flags to be flown simultaneously. In moto 2, Cianciarulo picked up right where he left off in the first race, coming around the first turn in second place. Cooper was in the lead once again until the Yamaha rider made a costly mistake in a deep rut, putting him off the track and allowing Cianciarulo to take over the lead, a position he would hold until the checkered flag flew. Cianciarulo's 2-1 moto finishes gave him the overall win and enabled him to extend his point lead to six over his nearest competitor.
