(NEXSTAR) — It's year four for NASCAR coming to World Wide Technology Raceway, but for the first time, they have a Cup playoff race, which has created some major buzz. So has the return of the Xfinity Series. Over the years, drivers like Dale Earnhardt Jr., Kevin Harvick, and Carl Edwards have raced and won at this track. "The Xfinity Series, as we are now, there's a lot of fans that might want to come to an Xfinity race that may not go to a Cup race," WWT Raceway owner Curtis Francois told Nexstar's KTVI. Saturday night under the lights, the Nu Way 200 was won by who else? Connor Zilisch. The 19-year-old from Charlotte has dominated this Xfinity season. It's a record-setting ninth win for him as he takes the checkered flag on Saturday night. "You know, I predicted myself with my crew chief at the beginning of the year that we'd win four, and that was being optimistic," Zilisch said. "To have nine is pretty incredible, and just, you know, thankful for my entire team." While Zilisch is grateful for his wins in the regular season, he's not looking to slow down at all during the playoffs. "The playoffs are everything. You win the championship in the playoffs, and that's when it really starts to count," Zilisch said. On the pole for Sunday's Cup race is Denny Hamlin, turning in the top time during qualifying. He's one of NASCAR's all-time Cup wins leaders with 58, with this being his 46th all-time pole start. The Round of 12 playoffs begin in Bristol, Tenn., next week with the Food City 300 at Bristol Motor Speedway. You can catch that race Friday, Sept. 12 at 7:30 p.m. ET live on The CW.
