Team Honda HRC’s Chase Sexton has halted the win streak of championship leader Eli Tomac, after the pair went head-to-head for two full motos at the Washougal round of the Lucas Oil Pro Motocross Championship.

When the dust settled, Sexton would win on count-back as he finished 2-1 to Tomac’s 1-2, while Monster Energy Kawsasaki’s Jason Anderson posted a brace of third-place results for third overall.

Monster Energy Star Racing Yamaha’s Tomac claimed a thrilling opening 450MX moto victory from his championship rival, Chase Sexton .

Red Bull KTM’s comeback king, Ryan Dungey, stormed to the holeshot from Sexton, Tomac and Anderson.

Sexton quickly charged into the lead, then three laps later, Dungey experienced a bike issue while running comfortably in second.

The mechanical DNF promoted Tomac into second and Roczen third. Tomac began turning the screws on Sexton, and as they distanced the rest of the field Tomac took the lead on the fifth lap.

Soon after Anderson passed Roczen for third, Tomac fell and collected Sexton at the same time. The pair desperately tried to restart, with them commencing battle at the same time, again with Tomac just in front.

The series leader would withstand a late desperate charge from Sexton to take the win, with Anderson and Roczen a distant third and fourth.

TLD Red Bull GasGas’s Justin Barcia would complete the top five.

Christian Craig (Monster Energy Star Racing Yamaha) recovered from a first-lap crash to finish sixth, ahead of Joey Savatgy (Monster Energy Kawasaki), Aaron Plessinger (Red Bull KTM), Benny Bloss (BBMX KTM), and Alex Martin (Muc-Off FXR ClubMX Yamaha).

The second moto saw Sexton bounce back for the win, but it started off the gate, as the early championship leader  scored a huge holeshot to start the second moto, followed by Tomac and Anderson.

The two championship front-runners quickly put daylight between themselves and Anderson, with the margin stretching and compressing as they went toe-to-toe in a classic race-long battle.

With three laps remaining, Sexton finally managed to pull a gap on Tomac and the points’ leader surrendered defeat as Sexton would take the win by 8.4 seconds.

Anderson crossed the line a distant third, while Dungey, who was outside the top 20 on the opening lap due to his poor gate pick, put in an impressive performance to finish fourth.

Craig, Roczen and Savatgy would finish fifth through to seventh, as Barcia, Bloss and Shayne McElrath (Rockstar Energy Husqvarna) filled the remaining top 10 positions.

In the championship fight, Tomac retains his five-point buffer over Sexton (364 points to 359 points) as the series heads into a two-week break, while Anderson continues his best-ever outdoor season in third, 79 points further back.

The ninth round of the Pro Motocross Championship will be held at Unadilla, NY on 13 August.
