Live updates from race at Las Vegas

Stage 3

Lap 271: William Byron wins! He uses the late-race restart to pass Martin Truex Jr. and outlasts his teammate, Kyle Larson. Byron led for 176 laps — including the right one. AJ Allmendinger is at the center of a wreck that collects a bunch of cars, but the race stays green so Byron can pass the start-finish line for the win.

Lap 265: Nothing easy! Kyle Larson sees his his three-second lead evaporate when Aric Almirola gets loose and drills into the wall and prompts a caution. Overtime. Restart incoming. William Byron edges Kyle Larson out of pit road. Larson has right-side tires. Martin Truex Jr. stays out. Top 4 now: Truex, Byron, Larson, Denny Hamlin.

Lap 245: Kyle Larson is dominating. This one feels reminiscent of his run at Miami-Homestead, when he got out in front and used that clean air and his pick of track positioning to keep extending and extending his lead. Larson has a 4.7-second lead over the rest of the field. His closest competition? William Byron, Denny Hamlin, Alex Bowman and Martin Truex Jr.

Lap 200: Kyle Larson passes Denny Hamlin on the outside, and now the 5 car has a 1.3-second lead over the rest of the field. Could that have been a race-defining move?

Lap 193: Denny Hamlin cycled out as the leader on pit road, and on the restart, he maintains the lead spot. The 11 team has one of the best pit crews in the sport — and that’s why he’s out in front. The Top 4 are racing each other hard: Hamlin, Kyle Larson, Alex Bowman, William Byron.

Lap 183: Caution is out! First caution for cause of the day. Joey Logano, who started on Sunday’s pole but has since fallen back to the middle of the pack, goes into a three-wide turn and appears to just run out of real estate. It ends in him knocking into Brad Keselowski — who doesn’t budge — and then hitting the wall and spinning out into the infield grass. No other cars were damaged in the spin. An update: Logano is now done for the day. He ran out of time on the damage vehicle policy clock.

Lap 174: And we’re green once more! If the race stays as clean and calm as it has today — which it almost certainly won’t — then this will be the last restart of the day.

Lap 170: All cars hit pit road, and the Top 4 remain in the lead. That’s William Byron, Kyle Larson, Alex Bowman and Martin Truex Jr. The Hendrick cars are going 1-2-3 — extending an already great day.

Stage 2

Lap 165: William Byron sweeps the stages in Las Vegas! Byron has been running with clean air all day. Will anyone challenge him in Stage 3? Still no cautions outside of stage breaks. Not much changed at the top of the field from Stage 1. Those earning stage points (in order): Byron, Kyle Larson, Alex Bowman, Martin Truex Jr., Christopher Bell, Bubba Wallace, Ross Chastain, Denny Hamlin, Brad Keselowski, Kevin Harvick. (Of note: Chastain was the leader in points heading into Sunday’s race, and he’s stealing points again today. The 1 car is having a phenomenal beginning to the season.)

Lap 127: A ton of clean racing, and we cycle through another handful of green-flag pit stops. William Byron still ahead by about two seconds over his teammate, Kyle Larson. Top 5: Byron, Larson, Ross Chastain, Christopher Bell and Denny Hamlin. That’s two Hendrick Motorsports cars, two Joe Gibbs Racing cars, and one TrackHouse Racing car. An update on Ryan Blaney: He was able to manage staying on the lead lap and is now running 17th and rising. The pit stop at the end of Stage 1 and subsequent ones under green have been fruitful; the car was nearly “undriveable” previously, Blaney said.

Lap 84: We have 22 cars on the lead lap. Ryan Preece will get the free pass in the new stage, which will make 23. Cars cycling through pit road. Denny Hamlin jumps up two spots because of it. The biggest news, though: Ryan Blaney came over the radio and said his car had a “massive” vibration, making it difficult to drive. More updates on this to come.

Stage 1

Lap 80: A caution-free first stage ends up being won by William Byron. That’s his first stage win of the year. Others in the Top 10 winning stage points: Kyle Larson, Ross Chastain, Christopher Bell, Denny Hamlin, Martin Truex Jr., Alex Bowman, Bubba Wallace, Kyle Busch and Brad Keselowski.

Lap 32: Some minor trouble! Kyle Busch, last weekend’s winner, knocked into the wall. The body looks OK, but Busch told the crew chief that there’s an issue with the steering. Now drivers are cycling through pit road. Ryan Blaney enters first. All cars getting fuel and four tires. A lot of rubber will be used today! (Also of note: Noah Gragson earns two speeding on pit road penalties — once on his first green-flag pit stop, the other on his penalty trip down pit road. Tough break for the 43 team.)

Lap 15: Solid racing in the early going. Already a bunch of passing. Top 10 running now: William Byron, Kyle Larson, Joey Logano, Ross Chastain, Ryan Blaney, Christopher Bell, Kyle Busch, Denny Hamlin, Brad Keselowski, Bubba Wallace. Hendrick cars looking great in the early-going, much like they were at Fontana last weekend (another intermediate track). (That last statement, of course, is true outside of Larson, who saw a one-off mechanical issue ruin his day.)

Green flag! 3:53 p.m.: Here we go!

3:49 p.m.: Las Vegas Motor Speedway is witnessing some 20 mile-per-hour winds that could wreak havoc today. The winds are steady, though, which is preferable to intermittent gusts. Green flag about to drop!

3:39 p.m.: Engines are fired (thanks to an enthusiastic Bryce Harper call), and drivers are now making laps. Race to start shortly!

2:48 p.m.: Some things to be on the lookout for: Harrison Burton will use a backup car after spinning and wrecking during practice on Saturday, and Tyler Reddick experienced engine issues on Saturday — so both of those drivers will start at the rear of the field. Also, Martin Truex Jr. will be without two crew members after losing his left-front wheel on the backstretch at Fontana last weekend.

2:42 p.m.: The biggest news from this weekend’s race at Las Vegas will involve someone who won’t be at the racetrack at all. Chase Elliott, NASCAR’s most popular driver, sustained an injury to his left leg and underwent successful surgery on Friday night after a snowboarding accident in Colorado. Hendrick Motorsports owner Rick Hendrick said Elliott is out indefinitely. That said, team officials still hope the No. 9 car is in playoff contention by this summer. Josh Berry will run in Elliott’s place today. It’s worth noting: Multiple drivers and officials have expressed empathy for Elliott, saying drivers “have lives outside the track” and sometimes accidents occur.
