FORT WORTH, Texas — Kyle Larson claimed the first of four championship-contending spots in NASCAR’s season finale with a dominating victory at Texas on Sunday to start the round of eight in the playoffs.

Larson led 256 of 334 laps at the 1 1/2-mile track and got his eighth win this season, staying in front through seven restarts in the final stage. Three of those restarts came after incidents involving other playoff contenders in the closing laps.

“This is unreal. I knew we’d have a good shot to win and our car was amazing. That was probably the best 550 package, intermediate package we’ve had all year,” Larson said. “We’re going to race for a championship. This is crazy.”

This was the first chance for anyone to guarantee a shot at racing for the Cup title in Phoenix on Nov. 7.

Already with a significant points lead, and coming off a win on the road course at Charlotte Motor Speedway a week earlier to close out the second elimination round, Larson left no doubt about the No. 5 Hendrick Motorsports Chevrolet being part of the championship four.

There were two laps remaining on the final restart, and Larson was able to stay in front of teammate William Byron.

“Kyle really deserves it, they’ve been awesome all year, flawless on pit road and they do everything right,” Byron said.

The seven remaining playoff contenders leave Texas with two more chances to get into the championship four, with races at Kansas and Martinsville left before the finale.

Ryan Blaney, Denny Hamlin and Kyle Busch are above the cutline going to Kansas, where Busch won earlier this year. Defending Cup champion Chase Elliott is fifth, ahead of Brad Keselowski, Martin Truex Jr. and Joey Logano.

Larson’s first appearance in NASCAR’s championship four comes in the same season that Rick Hendrick gave him an opportunity to get back into the Cup Series. He also won at Texas in the $1 million, non-points All-Star race in June.

The 29-year-old driver, who made his Cup debut in 2013, also won in his previous All-Star race, in 2019 with Chip Ganassi Racing. But he missed the 2020 big-money exhibition and the rest of that season while serving a six-month suspension after using a racial slur during a livestream while in a virtual race when NASCAR was on pause during the pandemic. That cost him nearly every sponsor, his seat with Ganassi, and nearly his career before Hendrick signed him.

Keselowski, whose fourth-place finish was the best among the other playoff drivers, provided the push from behind for Larson on the final restart.

“Well, we didn’t need all those yellows,” Keselowski said. “We needed the long runs to be able to keep them honest. We had long-run speed, but the 5 and 24 were just blistering fast on the restart and drove away from me. I just wanted some laps to let their stuff wear down.”

Hamlin was on the outside of a three-wide situation with 20 laps remaining when Blaney made contact with the No. 11 Toyota. The tire rub eventually blew, and sent Hamlin into a spin, though he was able to get to pit road and stay on the lead lap. Hamlin had more contact later that damaged his splitter.

“We just didn’t have a fast enough car. I thought we were probably fifth at best, honestly, and then two wrecks at the end,” Hamlin said. “This car is destroyed.”

Truex, Hamlin’s teammate at Joe Gibbs Racing, was later done after contact with Daniel Suarez that sent him hard into the wall.

Logano, who was already eighth in points, was the first of the playoff drivers out at Texas when his engine blew with 34 laps to go.

“Now we know what we have to do the next two weeks … we’ve got to go find a way to win,” said Logano, who is 43 points under the cutline.

Busch was the only playoff contender in the vicinity of a huge backstretch crash only 31 laps into the race, though he took only some minimal contact on the back of the No. 18 Toyota when scooting through the melee. He was back in the field after serving a penalty for speeding on pit road during the competition caution. He took more new tires as a precaution, then went on to win the first stage.

“I mean we probably missed four or five points there at the end of the day, but we missed four or five points at the stage as well too. So that’s what we missed out on,” Busch said. “Certainly the 5 and the 24 were the class of the field again. You know, we’re just slow.”
