Round four of the Pro MX Nationals traveled to the East Coast and visited the legendary High Point Raceway in Mt. Morris, Pennsylvania. And while the 450 class results were the same as they were are, we were treated to a special victory by Monster Energy/Pro Circuit/Kawasaki's fill-in racer Ty Masterpool. There's something special about a racer's first career win, but making this one even more memorable was that it was the Pro Circuit race team's 300th victory!
