2021 Arlington 1 Supercross Rnd 10 Results: Cooper Webb (Red Bull KTM) made a statement victory tonight in Arlington, Texas, and, as a result, took over the points lead after round 10 of the Monster Energy AMA Supercross Championship. A wire-to-wire win boosts him seven points ahead of championship rival Ken Roczen with seven races left in the championship.

The 450SX main began with Dean Wilson (Rockstar Energy Husqvarna Factory Racing) grabbing the holeshot over the championship contenders. Webb (Red Bull KTM) quickly forced his way to the lead in turn two and began to check out on the field.

Webb’s title rivals Ken Roczen (Honda HRC) and Eli Tomac (Monster Energy Kawasaki) were buried in the pack at the start of the race, crossing the line on lap one in 11th and 16th place, respectively.

Dylan Ferrandis (Monster Energy Star Racing Yamaha) found himself in a podium position early in the race, a close second behind Webb.

Justin Barcia (Red Bull TLD GasGas) started the race in third place but quickly made his way around Ferrandis for the second spot.

Roczen sensed urgency as his main competitor lengthened a lead over the field. He moved into eighth just before the five-minute mark.

Malcolm Stewart (Monster Energy Star Racing Yamaha) and Jason Anderson (Rockstar Energy Husqvarna Factory Racing) found themselves locked in a battle early on and exchanged aggressive block passes in the tight 180-degree turns. Stewart eventually found himself on the ground after a pass attempt went wrong. He would go on to finish 14th on the night.

Five minutes into the race Webb remained out front with a three-second lead over Barcia.

Chase Sexton (Honda HRC) found himself shuffling for the third spot in just his second race back from injury.

Anderson continued his march through the field and made another solid pass on Ferrandis.

The pass put Ferrandis on the ground, and he would pull off after another rider ran over his bike. The early-season podium finisher logged a 22nd place finish on the night.

Dean Wilson, meanwhile, made good use of a start in the 450SX main tonight. He ran inside the top five for most of the race, battling with heat race winner Aaron Plessinger (Monster Energy Star Racing Yamaha). The two traded spots for a solid portion of the race, and Wilson would eventually finish ninth.

Near the halfway mark, two of the three championship favorites were still outside of the top five. Roczen found himself stuck in seventh behind the Wilson-Plessinger battle, while Eli Tomac was further back in ninth.

Anderson secured the final podium position from Sexton with only eight minutes to go.

Joey Savatgy had a breakout ride tonight, hanging with Roczen early on in the race. He continued to ride near the front and passed Wilson for the seventh spot with five minutes left in the race.

The final laps remained consistent with Webb holding a strong three-second lead over Barcia and Anderson. Roczen solidified his spot in sixth, while Tomac moved into eighth with only two minutes on the clock.

Webb claimed the victory in a wire-to-wire win with Barcia and Anderson rounding out the podium. This victory catapulted Webb into the points lead, now seven points ahead of Roczen.

“This is an incredible night,” Webb said. “I got a bad start in the heat race but I made some passes and ended up third. In the main event, I got a great start and made my way into the lead early on and I led every lap. It’s awesome and it feels great to have these Texas fans here. It was a huge night and to get the red plate is great, I’m super grateful.”

Sexton and Plessinger would finish fourth and fifth, respectively, ahead of Roczen.

For Roczen, was his worst result of the 2021 season.

Marvin Musquin (Red Bull KTM) was today’s fastest qualifier but did not line up for the main event after a hard crash in the heat race that required medical attention. According to his team, he was transported to the hospital for evaluation but no further details were revealed.

Hammaker Gets His First In 250SX West Main Event

In just his third pro race, Seth Hammaker won his first 250SX main event.

250SX West

Supercross rookie Seth Hammaker (Monster Energy/Pro Circuit/Kawasaki) entered the main event after winning his heat race earlier in the night. The youngster holeshot the 250SX West main event ahead of his teammate Jordon Smith and Honda HRC’s Hunter Lawrence.

The two Kawasaki riders swapped positions during the opening two laps, with Hammaker taking control over his Team Green stablemate.

Looking to close the gap to the leader, Smith made a huge mistake just before the triple jump and was forced into “no man’s land” between the triple and the rhythm lane. Smith was able to jump back on track only after Lawrence passed for second place.

Similar to the 450SX class, both championship leaders were buried in the back of the field. Cameron McAdoo (Monster Energy/Pro Circuit Kawasaki) and Justin Cooper (Monster Energy Star Racing Yamaha) had their work cut out for them as both riders were forced to battle through the pack.

Hammaker quickly opened up a two-second lead over Lawrence and continued to ride with poise as the laps wore on.

McAdoo was one of the fastest riders on the track and caught up to the back of his Pro Circuit teammate, Smith. Smith’s rear-wheel spun off the face of a rhythm section and spit him off the side, taking a front wheel to the chest in the process. He was slow to get up but did finish the race in the last position, torn jersey and all.

The field remained sedentary for the latter half of the race. Lawrence was closing the gap to Hammaker and set the fastest time of the race in the process. With time running out and lapped riders in the mix, Lawrence was unable to advance.

Cooper and McAdoo were wheel to wheel with two laps to go. Both riders were reluctant to give up any championship points, and Cooper looked to force the issue in the penultimate corner. He barely clipped the last jump of the rhythm section which unsettled the bike and sent him to the ground. He remounted quickly but handed the final podium position to his championship rival.

Hammaker lit the candles for his first career win in only his third professional start.

Lawrence and McAdoo rounded out tonight’s podium.

McAdoo extended his points lead to six over Cooper.

Lawrence grabbed his first career Supercross podium and now sits third in the overall points.

Cooper Webb, Dylan Ferrandis and Eli Tomac round out the top five.

Points leader Ken Roczen had the sixth-best time.

Martin Davalos, Chase Sexton, Malcolm Stewart and Dean Wilson completed the top 10 qualifiers.

The first nine riders are all covered by one second.

Musquin said the whoops are a little tricky but overall he added that the track isn’t overly difficult, which should provide close racing tonight.

Sexton is riding well despite spending a large portion of the week at the dentist’s office after slamming his face on the handlebars last week at Daytona. In fact, he had stitches in his lip removed today at the track.

Shane McElrath isn’t riding today after announcing he is dealing with a back issue.

Justin Cooper found the right combination of speed and bike set-up to top 250SX West qualifying. The Monster Energy Star Racing Yamaha Team rider was a half-second quicker than runner-up Monster Energy/Pro Circuit/Kawasaki’s Seth Hammaker.

The new red-plate holder, Cameron McAdoo (Monster Energy/Pro Circuit/Kawasaki), last week’s Daytona winner, was third quickest, followed by his teammate Jordon Smith and Honda HRC’s Hunter Lawrence. It’s a good start for the Monster Energy/Pro Circuit/Kawasaki Team with all three of its riders qualifying in the top four.

Recently crowned Arenacross Champion Kyle Peters, who won every race in the championship, qualified 12th, a little over a half-second behind Cooper. CN
