Monster Energy AMA Supercross, an FIM World Championship series, kicked off a triple-header at Atlanta Motor Speedway with a daytime event where Monster Energy Kawasaki’s Eli Tomac used speed and patience to pull off a dramatic win, his third of the season, in front of the limited-capacity, pod-seated fans.

In a heart-breaking loss, Team Honda HRC’s Chase Sexton led for over four laps before a run-in with a lapped rider cost him the lead with the white flag in sight.

Series points leader Red Bull KTM’s Cooper Webb ran in second early in the race but had to settle for a third place finish when the checkered flag came out.

Atlanta Motor Speedway hosted the Western Regional 250SX Class for the first time in 36 250SX regional events in Atlanta, and rookie Monster Energy Star Racing Yamaha’s Nate Thrasher dominated the field at Round six of that regional championship’s 2021 nine-round series. The Western Regional 250SX Class delivered its fourth first-time winner this year with Thrasher’s dominating ride.

Thrasher nearly grabbed the holeshot even with a poor gate pick due to a trip through the Last Chance Qualifier. Once into the early lead the Yamaha rider looked picture perfect on the slick red dirt. Thrasher held on without any major mistakes through the 13-minute plus one lap event; a 2-minute abbreviation due to a schedule affected by the mid-day rain and mud.

Thrasher’s teammate, Monster Energy Star Racing Yamaha’s Justin Cooper earned a second place finish to stretch his points lead to four over third-place finisher Monster Energy Pro Circuit Kawasaki’s Cameron McAdoo. Cooper was sore from a heat race crash and benefited from a late-race crash from ClubMX/IAMACOMBACK/Yamaha’s Garrett Marchbanks. The podium finish gave Cooper two more points in the championship battle over McAdoo, who had a wild Main Event.

After grabbing the holeshot, McAdoo got shuffled back. The Kawasaki rider moved aggressively forward but a crash in the whoops three and a half minutes into the race ended his early charge to get back into the lead. McAdoo recovered to round out the podium.

The second race of Atlanta’s triple-header drops the gate on the final SuperTuesday event of the season on April 13, then wraps up the Atlanta residency on Saturday, April 17. Tickets for the Atlanta races as well as the final two rounds in Salt Lake City, Utah are available in a limited capacity, pod-seating format.
