Jett Lawrence sweeps Indianapolis Triple Crown for overall win, Cameron McAdoo takes the 250s.

Jett Lawrence entered Round 10 in Indianapolis, Indiana with one thing left to prove; he had only one Triple Crown win in the 250 class and struggled in this format in Anaheim, giving voice to speculation this might be his Achilles Heel. No one would have known about those struggles by the way he raced Saturday night.

With a perfect evening, Lawrence became only the second rider to ever sweep this format.

Ken Roczen was the first to sweep when he won the 2020 Glendale Triple Crown.

"It was awesome tonight for how brutal the track was," Lawrence told NBC Sports' Will Christien. "The bike was awesome. Got good starts all three. Just happy with the team."

Cooper Webb had trouble in the first race after he was involved in a crash with a lapped rider. He finished eighth in that race and then finished fifth and fourth in the next two, which placed him fifth overall. That allowed Lawrence to amass a 21-point gap on second in the championship standings.

Webb no longer controls his fate. He will need to Lawrence to finish worse than second in at least one of the final six races of 2024.

The three races had a familiar pattern with Ken Roczen getting the early lead in each with Lawrence patiently stalking him. Roczen was second overall with a 2-2-3.

"You kind of just play things by ear," Roczen said from the podium. "Every time I jump a jump I look ahead and pick a rut, but that's what makes it so hard. You just never know on the takeoffs."

Chase Sexton finished third in the first two races and got around Roczen late in the third to finish second. He was third overall.

Sexton is now one full race back of Lawrence with a points' deficit of 25.

Jason Anderson finished fourth with a 5-6-5.

In the 250 class, Cameron McAdoo finished first in Race 1, second in Race 2 and third in the final race to take the overall win. Having entered Indianapolis one point behind Tom Vialle, he earned enough points to grab the red plate.

"It means so much (to win)," McAdoo told NBC Sports' Jason Thomas. "It's been a while since I got a win. They all feel so good. I don't want to be redundant or repeat myself, but I'm so grateful to be in this position, to be this healthy, to fight for this."

Equally important, McAdoo shook off the bridesmaid role after finishing second in three consecutive races. The 250 West riders return to action next week in Seattle, so McAdoo can revel in his success.

Vialle had a little too much ground to make up after finishing fourth in the first race. He podiumed in Race 2 and won the finale.

Haiden Deegan crashed unassisted in Race 3 but charged back through the field to finish sixth. Along with his second in Race 1 and victory in Race 2, he finished third overall.

Pierce Brown finished fourth overall with a 12-4-2.

Supercross' toughest competitor of the week, Coty Schock finished fifth overall with a 5-8-8. He underwent surgery only five days ago to repair a broken collarbone. This is Schock's second top-five of the season.

Race Notes

Dylan Ferrandis is out of this round due to illness.

Jett Lawrence became the first rider this year with back-to-back wins and the field needs to keep him in sight if they expect to make a run for the championship.

Hunter Lawrence is back after a short time away for a shoulder blade injury.

The track is tight and technical.

Remember that Eli Tomac is the king of Triple Crowns with seven overall wins. For more stats, check out this week’s By the Numbers post.

Features

450 Race 3

In what has become a familiar pattern, Roczen takes the early lead with Jett chasing.

Lawrence isn't racing with the same sense of urgency as he did in the first two features since he doesn't need to win this one to take the overall.

Sexton has caught Lawrence and forces him to pick up the pace. They have both now caught up to Roczen.

Three minutes to go and Lawrence races Roczen side-by-side for nearly a lap before taking the lead.

Sexton is still third.

If Lawrence wins this feature, he will become only the second rider to sweep a Triple Crown. (Roczen swept Glendale in 2020.)

Lawrence wins to put to rest any thoughts that he has a weakness.

Sexton held on and finished second with Roczen third.

Webb finishes fourth in this race with Anderson fifth.

Best battle on the track right now belongs to Webb in fourth, Plessinger in fifth and Anderson in sixth.

250 Race 1

The first of three 10-minute features is underway with rookie Bennick taking the early lead.

Bennick bobbles and allows McAdoo to get the lead.

After losing his momentum, Bennick also lets Vialle and Deegan past — then Bennick falls and drops outside the top 10.

Fourth-place Hammaker is more than 13 seconds behind his teammate McAdoo.

With less than a minute on the clock, Vialle goes down. He got off rhythm in the whoops.

Qualification

Qualification takes on added importance this week because it largely decides who makes the night show. The Triple Crown format does not have heat races so riders really want to be one of the 18th fastest to head directly into the features. Four more will come from the Last Chance Qualifier.

450s

In Qualification 1, Webb had a slight tip over halfway through the session but comes back to post the 11th-fastest lap the next time by.

Race Day Live reports Roczen also fell briefly in the sand.

With most of the riders setting fast times late, Justin Cooper (48.671) landed on top. Cooper says the concrete is beginning to peak through at the bottom of some of the ruts.

Sexton (48.805) and Tomac (48.820) round out the top three.

Lawrence was fourth with Roczen fifth.

Mitchell Harrison (52.573) is 18th in Group A. Group B riders were unable to crack the 53 second mark. Clason is 19th so he needs to find a little more speed in Qualification 2.

Lawrence (48.523) finds the rhythm and jumps to the top of the board in Qualification 2 and overall.

In this session, Tomac is second fastest with Webb third.

Roczen is fourth in Qualification 2 and third overall with Anderson rounding out the top five on both lists.

Down on the bubble, Harrison took the 18th position in the combined session with Kyle Chisholm and Anthony Rodriguez just below the line.

250s

In Qualification 1, Anstie (49.492) and Vialle (50.065) posted their fastest laps at the end of the session to top the chart.

Brown (50.263) had the fastest speed for much of the session but landed third. He picked up the pace on the final lap, but not quite enough.

Hammaker and Deegan round out the top five.

Remarkably, Schock is back on track only five days after surgery. He's fast enough for now to make the evening program with the 11th fastest time.

Ryder Floyd is 18th with Preston Boespflug on the outside looking in.

Free Practice

450s

There's a reason Roczen (49.329) loves to come to this track. He's fastest in the first practice session over Anderson (49.510) and Justin Barcia (49.660).

Remember that Barcia has a great record in Indy also with second-place finishes in each of the last three years.

Cooper and Tomac round out the top five.

Jett Lawrence is well down in 11th, but no one expects that to last.

Hunter Lawrence was 15th on the chart in his return.

250s

It appears Deegan (50.121) is putting controversy aside. He tops Free Practice by a margin of .129 seconds over Vialle (50.250).

Anstie (50.316) rounds out the top three.

McAdoo and Bennick land fourth and fifth.
