Kyle Larson caps 10-win season with first NASCAR Cup Series championship - USA TODAY

Larson won his first NASCAR Cup Series championship, capping a 10-win season with a victory in the season finale.

Larson's momentous season comes just one year after the Hendrick Motorsports driver was suspended by NASCAR and fired by his former team for using a racist slur during a live-streamed iRacing event in April 2020.

Larson held off Martin Truex Jr. by 0.398 seconds, as the 2017 Cup champion closed in on Larson in the final laps.

The other two Championship 4 contenders were not far behind. Denny Hamlin finished third and Chase Elliott finished fifth. Ryan Blaney came home fourth, the first of the non-playoff drivers.

Hamlin, who found speed during the second half of the race, tried to close the gap on Larson and Truex following the final restart but ultimately ran out of laps. He praised Larson, offering the new champ "Special congrats."

Larson's pit crew has been stellar all year, and they shined again on a pit stop following a caution on Lap 283 for David Starr. The No. 5 Hendrick Motorsports crew helped Larson gain three positions during pit stops as Larson launched to the lead from the No. 1 pit stall.

Larson and Hamlin restarted on the front row with Truex and Elliott on row 2, and Larson took off with the lead. Truex surged as well, though, and passed Hamlin to take over second.

The third stage took its first turn just as green-flag pit stops began.

While running fourth behind the other three title contenders, Truex and his team opted to pit on Lap 247, and they caught a big break. While Truex's pit crew was servicing his car, Anthony Alfredo triggered a caution after plowing into the outside wall.

But the 19 pit crew was able to get Truex back on the track before the leaders crossed the start-finish line, and that made a huge difference. 

When Elliott, Hamlin and Larson pitted, Truex cycled to the lead, and led the field to a restart on Lap 255. The other three championship drivers restarted in the top 10, and by Lap 260, all four title contenders were running 1-2-3-4 again.

After the Championship 4 drivers, Ryan Blaney, Kevin Harvick, Brad Keselowski, Kyle Busch and Joey Logano closed out the top-10 in the second stage.

Ricky Stenhouse Jr. and Chase Briscoe were among the drivers to wreck during the stage.

Truex took the green-and-white checkered flag after 75 laps to win the first stage. Of course, in the championship race, points don't matter for the Championship 4 drivers, but all four title contenders, led by Truex in his No. 19 Joe Gibbs Racing Toyota, showed strong early speed.

Truex stole the lead away from Blaney on Lap 51 and held onto it through the end of the stage.

Harvick, who like Blaney, was previously eliminated from the playoffs, finished second and was followed by the other three title contenders: Elliott, Hamlin and Larson, respectively, in the top five.

William Byron, Cole Custer, Blaney, Kurt Busch and Matt DiBenedetto rounded out the top-10 finishers.

Understandably frustrated, Wallace exited his toasted car, and as LaJoie passed him again on the track under caution, Wallace clapped his hands at the No. 7 driver.
