LAS VEGAS On Friday night, Justin Allgaier saw the Eagles in concert. On Saturday, he was flying.

Holding off Aric Almirola over a 102-lap green-flag run, Allgaier finally claimed victory at Las Vegas Motor Speedway after finishing second four times at the 1.5-mile track.

Allgaiers victory in The Liuna! was his first of the season, the 26th of his career and the 90th for JR Motorsports in the NASCAR Xfinity Series. The reigning series champion crossed the finish line 1.067 seconds ahead of Almirola, who lost ground trying to run the outside lane with just over three laps left.

The decisive moment in the race, however, may have come much earlier. Allgaier lost the lead to Almirola during an exchange of pit stops midway through the final stage, but he regained it in traffic on Lap 152 and remained out front the rest of the way.

With the victory, Allgaier qualified for the first Xfinity Dash4Cash race next Saturday at Homestead-Miami Speedway, along with third-place finisher Jesse Love, fourth-place Austin Hill and fifth-place Sam Mayer. The highest finisher among the four earns a $100,000 bonus.

Almirola isnt scheduled to run the Homestead race.

It was amazing, said Allgaier. This whole teamI just cant say enough. Aric and I were going at it. Hats of to him; he ran a heck of a race

Rick Brandt (of sponsor Brandt) was here last night. He took us to a great concert, Eagles concert Everyone at JR Motorsports, I cant say enough about how proud I am of what we have here. Its been special.

After Allgaier took the lead on Lap 152, he opened an advantage of more than two seconds over Almirola, who spent the next 40 laps whittling the margin down to a car-length. But Almirola couldnt find a way past Allgaier in the closing laps.

You always hate to finish second, but Justin and that team was I felt like the class of the field today, Almirola said. We were close, but they could just take off so much faster than I could. I think thats really the difference.

I thought my only hope was to cycle in front of him on the green-flag stop, and we did, but I just got caught up behind some lapped traffic there that I misjudged. I wasnt sure which way they were going, and he got by me and built such a big gap that I used my stuff up trying to get back to him.

The green-flag stops in the final stage proved costly to Sunoco rookie Connor Zilisch, who streaked into the lead on Lap 100 and held it until Allgaier nosed ahead at the start/finish line on Lap 127.

During the stops on Lap 145, however, Zilisch drew a speeding penalty and served a pass-through that dropped him to the back of the lead lap. He rallied to finish ninth, the last driver on the lead lap.

Allgaier led 102 of the 200 laps, followed by Almirola (51) and Zilisch (28). Brandon Jones, Ryan Seig, Harrison Burton, Zilisch and Sheldon Creed completed the top 10.

Allgaier, who won the first stage by 8.262 seconds and finished second in Stage 2, took over the series lead by 19 points over Love.
