Sam Mayer wins Xfinity Series race at Texas in photo finish over Ryan Sieg

In a race decided by less than the length of a Texas hot chili pepper, JR Motorsports driver Sam Mayer pulled off a last lap pass of veteran Ryan Sieg to claim his first victory of the season Saturday in the Andy’s Frozen Custard 300 at Texas Motor Speedway.

Officially, the margin of victory was .002-second as Mayer’s No. 1 JR Motorsports Chevrolet and Sieg’s No. 39 Ryan Sieg Racing Ford crossed the finish line door-to-door, bumper-to-bumper – the cars so close officials took a brief extra look to formally declare Mayer the winner. It was Mayer’s first win of the year and fifth of his career.

It would have been Sieg’s first win in 342 career starts in the series.

“That’s absolutely unreal,” the 20-year old Mayer said, shaking his head after climbing out of his car. “This team, the amount of adversity we’ve had to fight this entire year so far and to come to a mile-and-a-half that I want to say I’m good at, but it took a lot.

“It took every ounce of me for me to do that today.”

Sieg led 17 of the final 18 laps and raced off to the front on a pair of late race restarts in the closing 20 laps of the 200-lap race on the 1.5-mile Texas high banks. With nine laps remaining Sieg held a 1.2-second advantage over Mayer. But Mayer cut into that margin with each lap, trailing by only .25-second with two laps remaining and then catching Sieg’s car on the back stretch on the final lap. They exchanged the lead briefly, racing door-to-door and then Sieg pulled alongside as they took the checkered flag in a photo finish – the closest ever for an Xfinity Series race at Texas.

“Awe, it sucks,” said an obviously disappointed Sieg, who has two other career runner-up finishes. “We had a really good car. I just got tight, so tried to change my lines, do everything. I saw him coming and I did all I could do and at the end I was just trying to run him up into the wall to try to win the race. We were so close. This sucks.

“I’ve been second before. Too many times. But this is a good thing, means we’re running where we need to be in the top-five.

“Just got to keep fighting, we’re right there, just got to keep it up,” he added. “We’ll have it in Victory Lane here shortly.”

All the late race drama came at the expense of veteran Justin Allgaier, who led a race best 117 laps and swept both stage victories, but ultimately finished third in the No. 7 JR Motorsports Chevrolet. It was disappointing DeJa’Vu for Allgaier, who a year ago led a dominating 133 of the 200 laps only to finish fifth.

A.J. Allmendinger finished fourth in the No. 16 Kaulig Racing Chevrolet – a huge rally for the perennial championship contender after he missed his pit stall during the Stage 1 caution, which put him back in the field and forced him to race through the field – again.

Reigning Xfinity Series champion Cole Custer, who started from outside the front row, was a top five car all day and finished fifth in the No. 00 Stewart-Haas Racing Ford. Custer now trails championship leader Chandler Smith – who finished 15th – by 19 points in the standings.

Two-race winner, Richard Childress Racing’s Austin Hill finished sixth, followed by Joe Gibbs Racing’s Ryan Truex, JR Motorsports Sammy Smith, polesitter, RCR’s Jesse Love and Anthony Alfredo, who earned his third top-10 of the season in the Our Motorsports No. 5 Chevrolet.

With the win Mayer not only course-corrects a rough start to the 2024 season – he suffered DNFs in three of the first four races – but he earns the coveted $100,000 prize from Xfinity as the Dash 4 Cash winning driver.

He’ll compete against Sieg, Allgaier and Allmendinger for the big Dash 4 Cash check again next week at Talladega (Ala.) Superspeedway.

It was a rally not just for driver but for his JR Motorsports team. The perennial championship favorite has struggled early in the 2024 season – its four talented drivers not earning a top-five until last week at Martinsville. On Saturday, not only did the team – co-owned by Kelley Earnhardt Miller and her brother Dale Earnhardt Jr. – win the race but all four cars finished in the top-13 and three of the four drivers (also Brandon Jones) led laps.

The NASCAR Xfinity Series heads to Talladega (Ala.) Superspeedway where it will race in the Ag-Pro 300 (4 p.m. ET on FOX, MRN and SiriusXM NASCAR Radio). Jeb Burton is the defending race winner.
