In dramatic circumstances, Red Bull KTM’s Cooper Webb stormed to the win at the Arlington round of the Monster Energy AMA Supercross.

Featuring the second Triple Crown round of the year, Webb, championship leader Eli Tomac (Monster Energy Yamaha Star Racing) and Jason Anderson (Monster Energy Kawasaki) all shared wins, as Webb, Team Honda HRC’s Chase Sexton, and Tomac filled the round podium.

Eli Tomac grabbed the holeshot of the first 450SX main event, and led to the checkered flag, despite constant pressure from Ken Roczen (Progressive Insurance Ecstar Suzuki) throughout the race.

Sexton put in the fastest laps of the race as he came from deep in the pack to finish a hard-fought third, ahead of Justin Barcia (TLD Red Bull GasGas) and Webb .

Webb’s Red Bull KTM team-mate Aaron Plessinger, Rockstar Energy Husqvarna’s Christian Craig, and fastest qualifier Jason Anderson – who initially remounted dead last after a first-turn crash – finished sixth to eighth.

Colt Nichols (Team Honda HRC) and Justin Hill (Team Tedder Monster Energy Mountain Motorsports KTM) filled the remaining top 10 places.

Jason Anderson took a 2.8-second win in the second 450SX race.

The Monster Energy Kawasaki rider claimed the holeshot, but temporarily surrendered the lead to Webb before retaking it one lap later and holding the rest of the pack at bay for the remainder of the race.

Webb held off a hungry Sexton for second, as race one winner, Tomac, finished fourth. Plessinger, Roczen, Barcia, Craig, Justin Cooper (Monster Energy Yamaha Star Racing) and Dean Wilson completed the top 10.

Cooper Webb won a thrilling final 450SX race that saw three different leaders, and claimed the round win in the process.

Tomac grabbed the holeshot and tried to pull away, but Sexton stayed with him before he washed his front wheel in a corner.

Although he didn’t lose a position, he soon inherited the lead when Tomac made an uncharacteristic error.

Webb put in a late-race surge to pass Anderson, then take advantage of a lapped rider to snatch the lead from Sexton and win the race.

Sexton and Anderson claimed the top three positions, ahead of Roczen and Plessinger. Tomac eventually finished P6, ahead of Barcia, Craig, Cooper and Hill.

In the championship standings, Tomac continues to hold a two-point lead over Webb, with Sexton a further three points back.
