The headline of Saturday’s race was probably one. Justin Allgaier, the 2024 NASCAR Xfinity Series champion, swept both stages and won his season’s third trophy. The Tennessee Lottery 250 at Nashville Superspeedway looked like his playground, as he deftly fought off his teammate, young prodigy Connor Zilisch, in the closing laps. However, this glorious story had a crazy, wild chapter that was a sequel to last year. It involved Chevrolet youngster Parker Retzlaff.
The 22-year-old Alpha Prime Racing driver came off a disastrous 2024 season, laden with 12 DNFs, to restart his 2025 season on a fresh note. However, it has been far from smooth sailing, and Parker Retzlaff faced a dilemma from the sibling of the rival he went up against last year.

Parker Retzlaff goes ballistic
During the 2024 Xfinity Series race at Sonoma Raceway, a wild incident unfolded. During the closing laps, both Ryan Sieg and Parker Retzlaff were hoping to grab top-ten finishes. Having finished a runner-up five times in his career with not a single victory, Sieg got overzealous and bumped into Retzlaff’s side. Then a hot-headed Retzlaff took a shot at his rival’s right rear and sent him spinning. The post-race beef was far from pleasant, with a slew of expletives thrown at each other. Exactly a year later, Retzlaff has reasons to be hot-headed again, but due to a different Sieg brother.
With the Xfinity Series grid barely done with Stage 1 at Nashville, chaos unfolded. On lap 35, Ryan Sieg’s brother, Kyle Sieg’s No. 28 Ford Mustang, got loose off Turn 4, got tight below Retzlaff in the corner, and lost it. He collided with Parker Retzlaff‘s No. 4 Chevrolet. That spun out the latter in a smoking wreck, and Retzlaff’s car backed into the wall. Retzlaff got ruled out of the race, his third finish outside the top-35 in four races. That is why Retzlaff let loose his fuming emotions targeting the Sieg name. He wrote on X, “Can’t be surprised it’s it’s always someone else’s fault must run in the family… mad because I was too close to him.”

Parker Retzlaff’s journey has been a mixture of highs and lows. The young speedster stumbled into the racing world with a literal bang. He learned to wrestle cars with more slide than grip on dirt tracks and made a legendary name for himself on iRacing with 1,150 victories. In 2023, Retzlaff outpaced Jeb Burton with 7 top-ten finishes. But that streak halted in 2024, and the slump has continued into 2025. Yet Retzlaff’s determination is unhindered, as he said at the start of the season: “I feel like we still have something to prove.” However, this season just made his misery worse.
What’s your perspective on:
Is Parker Retzlaff's fiery attitude a strength or a liability in his NASCAR career?
Have an interesting take?
Retzlaff’s most embarrassing moment of the season came at the Circuit of the Americas, where the driver failed to qualify for the race! He posted a sobering apology on X, writing, “I don’t even know what to say. Never in my life was this even a thought. I’m sorry to my team, my sponsors and everyone who supports me.” So, while Retzlaff gets frustrated by antics on the track, he also knows that as a driver, there’s a lot of scope to improve.
However, despite personal results, the beef between Parker Retzlaff and the Sieg brothers is persisting. In fact, there was more than one incident in 2024.

When the rivals caught others in the chaos
Well, Parker Retzlaff got mad at a Sieg brother at Sonoma and Nashville, yet his car made contact with a Sieg car at Pocono Raceway as well. During the 2024 Explore the Pocono Mountains 225 race, things got out of hand on a lap 46 restart. The field fanned out three and four wide heading into Turn 1. As Kyle Sieg and Retzlaff reached Turn 1, they could not pass that crowd without contact. As Retzlaff made contact with the left rear of Sieg’s car, it got Retzlaff’s car out of shape.
Retzlaff slid up the track to the left, spurring a multi-car melee that involved several drivers like Leland Honeyman, Ryan Ellis, and Brennan Poole. Ellis was the driver who suffered the biggest hit in the crash, He had to retire from the race because of the extensive damage he sustained on the No. 43 Alpha Prime Racing Chevrolet. Clearly, the beef between Parker Retzlaff and his Sieg rivals has collateral damage as well.
Nevertheless, Retzlaff is highly motivated as he has strong support on his side. After his first encounter with Ryan Sieg at the 2024 Sonoma race, fans were in his favor. What is more? Retzlaff’s team owner, Caesar Barcarella, and Tommy Joe Martins believe in him. Barcarella said at the end of 2024: “There’s been a lot of ups and downs, but he [Tommy] and I agree it’s all about the people. It’s so hard. We’re racing against the best teams in the world. But we’ve got great people, and that’s what’s made it work.”
