A year after becoming the youngest race winner and youngest rookie of the year in series history, he became the youngest series champion.
Kwasniewski entered the event with a two-point lead over teammate and defending series champion Greg Pursley in one of the closest championship battles in the history of the series.
“All we had to do was finish in front of Greg and that’s what we did,” Kwasniewski said. “I couldn’t be more proud of my team and my mom. My dad started all this for me and this race was for him and this championship is for him,” Kwasniewski said of his late father. “To be out here in Phoenix and to get the championship, there’s no better feeling.”
Michael Self, who started the race on the outside of the front row, shot into the lead at the drop of the green flag and paced the entire 50 laps to score his third career win – all this season.
At 17 years 5 months 10 days, Kwasniewski eclipsed the previous record set by Chuck Bown in 1976 at 22 years, 7 months, 11 days.
