NASCAR Pennzoil 400: Alex Bowman wins at Las Vegas Motor Speedway

NASCAR's best took to Las Vegas Motor Speedway on Sunday for the Pennzoil 400 presented by Jiffy Lube.

Coming off a win at Auto Club Speedway last weekend, Kyle Larson was looking for back-to-back wins in the beginning stages of the season — but Alex Bowman had other ideas, aided by a late caution flag.

Here are the top moments from Sunday at the racetrack:

Familiar faces

Before the action on the speedway got underway, Danica Patrick made an appearance to discuss being a spectator and a broadcaster of the sport she once competed in.

There was also an appearance by former NFL MVP Marcus Allen.

Less than ideal start

Larson entered the race riding a wave of momentum after last week's win, but a second stop has set him back early on in Las Vegas.

Early caution

Less than halfway through Stage 1, Cole Custer spun out, causing an early caution on Lap 38.

Kyle Busch nearly found himself in the same predicament, but was able to use a half-spin to stay safe on the track.

Leading man

With 30 laps left in the opening stage, Denny Hamlin grabbed the lead.

Tempers rising

There was no love lost between Kyle Busch and Chase Briscoe on the speedway, and Busch wasn't scared to let his feelings be known.

Swerving Suarez

Briscoe had issues with Busch earlier, and he inadvertently caused Daniel Suarez to collide with the wall later on.

Making it look easy

Kyle Larson entered the race on Sunday as the man of the hour, and as the race progressed he showed exactly why he is one of the best in the business.

Down goes the defending champ

After winning in Vegas in the fall, Denny Hamlin will not be repeating as a winner at the Las Vegas Motor Speedway after a rough day on the track.

Costly finish

With only a handful of laps left in the race, the day ended abruptly for both Erik Jones and Bubba Wallace due to Jones hitting the wall and Wallace swerving off the road to avoid hitting him.

We have a winner

When the smoke cleared and the dust settled in Las Vegas, Alex Bowman was victorious, racing past Larson and the field to edge out a narrow victory.
