After going 0-for-26 in the 2021 NASCAR Cup Series regular season, Denny Hamlin is 2-for-2 in 2021 playoff round openers. After winning the first race in the Round of 16 at Darlington three rounds prior, he dominated the Round of 12 kickoff at Las Vegas Motor Speedway as he led 137 of 267 laps en route to his maiden win at the track.
Kyle Larson, who won last week at Bristol, was on the pole but second-place starter Ryan Blaney had the early advantage to lead seven laps before Hamlin did so until the lap 26 competition caution. Although Hamlin continued to lead on the restart, Larson was in front by lap 45 and held it to the end of the segment. Kyle Busch, Hamlin, Blaney, William Byron, Chase Elliott, Tyler Reddick, Kevin Harvick, Matt DiBenedetto, and Martin Truex Jr. rounded out the top ten. All but Reddick and DiBenedetto were in playoff contention, and Byron and Truex had started the night at the rear for multiple pre-race inspection failures (as did Aric Almirola and J.J. Yeley).
Five circuits into Stage #2 on lap 93, Joey Gase would be involved in the race’s lone wreck in major fashion when his left-rear wheel came off in turn two and caused him to spin and slam into the outside wall, briefly sending his car airbourne. The crash resulted in hospitalisation for further evaluation. Neither the team nor NASCAR have provided updates at the time of this article’s publishing.
Larson led on the restart and dominated the rest of the stage. However, he was among those who pitted under green shortly before the segment’s conclusion and cycled the lead to Reddick and Hamlin. The latter would take the stage win ahead of Busch, Reddick, Truex, Joey Logano, Brad Keselowski, Kurt Busch, Harvick, Austin Dillon, and Bubba Wallace.
The 101-lap Stage #3 ran completely green. Hamlin led before the next green-flag pit cycle opened on lap 210, which rotated the top spot to Reddick, Keselowski, and Dillon. Dillon led the most of the trio with seven laps, his highest lap-led count of the season and a personal best at Las Vegas (beating his two in 2016), before relinquishing first back to Hamlin on lap 229.
