After missing almost the entire 2016 Lucas Oil Pro Motocross Championship recovering from a fractured vertebra sustained during the supercross season, Hayden Mellross returned to racing in strong form at Unadilla’s 10th round of the series. The young Australian 450 Class contender chalked up an impressive 20-16 moto scorecard to walk away with 17th overall for the day on what many have said to be the most challenging circuit of the year.
