In the 250 East race it was the two championship leaders in Pro Circuit Kawasaki's Austin Forkner and Rockstar Husqvarna's Zach Osborne who exited the first turn side by side, with Osborne being credited with the holeshot, but Forkner quickly taking over the race lead.
With the two riders heading into the round tied on points, it looked as though Forkner was going to be the rider that left St. Louis with the points lead as he edged slowly ahead.
At the halfway point of the race, Osborne closed the gap to Forkner, pressuring the young rider into a mistake that left him on the deck. Osborne took full advantage of the situation and raced to a clear win.
Forker quickly remounted and was making up time, but another lapper forced him to fall and stall the bike. Undeterred and knowing each position counted, Forkner pushed as much as he could to make it back into the top-five to keep his championship hopes alive.
Geikco Honda's Jeremy Martin crossed the line in second position, with Troy Lee Designs KTM pilot Jordan Smith rounding out the podium.
JGR Suzuki's Kyle Peters finished in fourth for his best rsult of the season.
In the point‰Ûªs standings, Osborne now holds a 8 point lead over Forkner, with Jordan Smith only 5 points further back in third.
