After finally getting his first career victory at Las Vegas Motor Speedway on his 21st try, Denny Hamlin is on an undeniable hot streak he just might ride all the way to his long-sought first NASCAR Cup Series championship.

Hamlin finally broke through in Vegas on Sunday night, holding off Chase Elliott and kicking off the second round of the playoffs with his second win in September.

Three weeks after Hamlin got his first victory of the season in the playoff opener at Darlington, he led 137 laps in Vegas in his Joe Gibbs Racing Toyota, including the final 39.

After a season of frustrating results and a 17-year career filled with championship near-misses, Hamlin has emerged as a serious contender for the title once again. He is just 14 points behind Kyle Larson in the points standings, and he’ll have no pressure heading into the high-stakes upcoming races at Talladega and the Charlotte Roval with his ticket already punched for the third round by this Vegas victory.

The 41-year-old veteran had struggled on this 1 1/2-mile track for most of his career, with just two top-five finishes in his first 18 starts. He has put together three consecutive top-four finishes since then in Vegas, capped by this victory under the lights and fireworks.

Kyle Busch finished third on his hometown track, followed by Martin Truex Jr. and Ryan Blaney as the 12 remaining playoff drivers began the second round and the final seven races of the season. Hamlin, Busch and Truex put Joe Gibbs Racing in three of the top four spots.

Larson finished 10th on the track where he won in March. Kevin Harvick, who scrapped with Elliott over tactics last week at Bristol, finished ninth.

The NASCAR Cup Series playoff race continues at Talladega next Sunday.
