LAS VEGAS — William Byron took the lead on the second-to-last lap of overtime to win the NASCAR Cup Series race at Las Vegas on Sunday and put an exclamation mark on a dominant day for Hendrick Motorsports.

The top three drivers were from Hendrick, with Byron beating teammates Kyle Larson and Alex Bowman. Bowman won last year’s March race at Las Vegas Motor Speedway.

Byron led 176 laps and won for the fifth time in his six Cup seasons.

Larson appeared headed for victory when when Aric Almirola hit the wall in turn four on lap No. 264, leading to the second caution of the day.

Most of the leaders pitted a lap later, with only Martin Truex Jr. choosing to stay out. Byron came out of pit road ahead of Larson and then easily overtook Truex on the restart.

Byron, who started in the first row with Joey Logano, swept both stages in the Hendrick Motorsports No. 24 Chevrolet for the first time in his career. Truex and Kevin Harvick also won both stages in Las Vegas and went on to win – both in 2018.

DEFENDING CHAMP HITS WALL

Logano, the defending Cup champion who won the Las Vegas race in October, hit the wall in in turn four on lap No. 183, ending his day. He was running three-wide with Brad Keselowski in the middle and Kyle Busch on the apron when Logano bumped into Keselowski, sending his Team Penske No. 22 Ford into the wall.

“I’m sure (Keselowski) didn’t mean to do it,” Logano said. “What are you going to do, right? We got fenced.”

It was a tough day all around for Logano, who was running 15th after starting on the pole.

“Considering how we’ve been here in the past, you kind of expect it a little bit more performance today than what we had,” Logano said. “Just off on overall speed. We had the balance somewhat close, just not fast.”

NO HOME-TRACK ADVANTAGE

Sunday’s first stage wasn’t kind to Las Vegas drivers Busch and Noah Gragson. Busch bumped the wall, and Gragson twice was penalized for speeding on pit road. Gragson later was docked a third speeding penalty.

Struggles in his hometown are nothing new for two-time Cup Series champion Busch, whose only top-level win at Las Vegas was in 2009.

Gragson is a Cup Series rookie.
