Connor Zilisch capped off a remarkable rookie season by winning the Nu Way 200 at World Wide Technology Raceway, securing the 2025 NASCAR Xfinity Series regular-season championship, and locking in the final 12-driver playoff roster.
The 19-year-old phenom, driving the No. 10 Chevrolet for JR Motorsports, dominated Gateway with his ninth win of the year, tying a modern-era rookie record.
Zilisch’s triumph at Gateway, where he started on the pole and led 112 of 160 laps, expanded his points lead to 29 over teammate Justin Allgaier.
Along with maximum playoff points earned from regular-season wins and stage victories, he now holds a massive 59 playoff points buffer, per NASCAR.com. His stellar run effectively ended any suspense around the regular-season title and set a thrilling tone for the NASCAR Xfinity Series playoff bracket 2025, which begins with the Bristol race.

Carson Kvapil clinched his spot based on points after winning at Portland, leaving Gateway to decide the final positions. Notably, Austin Hill, despite three wins, enters the playoffs with zero playoff points following a suspension that stripped his bonuses, placing him near the bottom of the playoff standings.
The tight point margins underscore the competitiveness of the NASCAR Xfinity Series playoff standings 2025, setting up a thrilling battle as the postseason begins.
Playoff Opener Bristol 2025 and Beyond
The playoff opener will take place at the Food City 300 at Bristol Motor Speedway on September 12, 2025, airing at 7:30 p.m. ET on The CW.
The Round of 12 will then continue with races at Texas Motor Speedway on September 20 and the Charlotte Roval on September 27. After the Roval, four drivers will be eliminated, narrowing the field to eight for the next round.
Connor Zilisch’s substantial playoff points advantage gives him some breathing room, but seasoned veterans like defending champion Justin Allgaier, with 119 career wins, and Austin Hill, seeking redemption, remain serious threats.
The emotional edge added by Harrison Burton’s clinch over his cousin Jeb brings a personal storyline as the playoffs unfold, with Harrison remarking, “Family makes it tough, but playoffs wait for no one.”
Rookies like Jesse Love and Carson Kvapil inject fresh energy into the playoffs, while Sheldon Creed is eager to claim his first title after coming close in past seasons. The 2025 NASCAR Xfinity Series has been characterized by parity and talent depth, with 15 different winners through 26 races, highlighting the competitive balance and uncertainty that make the playoff rounds so exciting.

With Connor Zilisch leading the charge, the 2025 NASCAR Xfinity playoff bracket promises fireworks, upsets, and possibly a fairy-tale ending for the rookie sensation who dominated the regular season.
