Perfect weather conditions at Pennsylvania's High Point Raceway brought out the best in the stars of the Lucas Oil Pro Motocross Championship, sanctioned by AMA Pro Racing, at the fourth round of the 50th anniversary season. The Lucas Oil Stabilizer High Point National represented this summer's East Coast debut during Father's Day weekend and featured the most closely contested battles for victory this season across both the 450 Class and 250 Class, where a tiebreaker decided the winner in each division.

450 Class

A dominant opening moto by Team Honda HRC's Chase Sexton suggested it might be his afternoon to make a big statement as the championship point leader. Instead, another stellar second moto performance by Monster Energy Star Yamaha Racing's Eli Tomac left the overall win in the balance. The multi-time series champion ended the day with the checkered flag to secure the tiebreaker and capture his 28th career win. Tomac also became the fourth different winner in the division in as many races.

250 Class

For the first time this season, a head-to-head battle between the Lawrence brothers decided the overall winner. The Australians set the standard once again with another 1-2 performance, their third of the season, but it was their stellar battle for the Moto 2 win, and ultimately the overall, that served as one of the highlights of the event. Jett and Hunter traded the lead several times in the closing stages of Moto 2, where Jett prevailed over his older brother by a mere half second to clinch the tiebreaker and a fourth straight win to open his title defense.
