The final day of the Superkarts! USA Pro Tour for the 2018 season went into the books on Sunday. The sixth and final round of the championship chase took place at the New Castle Motorsports Park to close out the ninth edition of the SummerNationals. Weather remained warm and humid, with no issues of rain sliding into the area to disrupt what was the closing laps of the 2018 SKUSA Pro Tour and deciding all nine champions for the 2018 season.

Coming into the weekend, the S1 Pro Stock Honda division was up for grabs. TB Kart USA driver AJ Myers entered the weekend third in the standings, riding on his victory at the WinterNationals. Myers, a double winner at the 2016 event, was runner-up on Saturday to help to close the gap on championship leader Billy Musgrave (MRC / Aluminos). Myers made sure to put things in his hands by dominating the day to score maximum points and earn his first SKUSA Pro Tour championship. Myers went untouched on the day, leading all laps in the Prefinal and Final along with fast laps of the race in both. 2017 champ Jake French (DKC / Sodikart) bounced back from a DNF in the Prefinal to advance seven spots to second, with Kyle Wick (RPG / CRG) completing the podium. Saturday winner Hunter Pickett (Sodikart) drove to fourth with Nic LeDuc (Sodikart) in fifth. Read full story on eKartingNews.com

The final event for the 2018 Superkarts! USA Pro Tour completed the opening day of racing at the New Castle Motorsports Park. The ninth edition of the SummerNationals ran without any weather issues, however, the day was along with LCQs and delays due to red flag during practice. The seven main events wrapped up just before 7pm with the sun setting over the pond straight, followed by the podiums. It was an exciting day as the fifth round of the championship chases were completed on Saturday.

The 78-driver field in the X30 Senior were split up in qualifying, while running two separate Prefinal for all the drivers. Former SuperNationals winner Marco Maestranzi (Top Kart) was able to end the fast group as the top qualifier with last year’s SummerNats winner Brandon Jarsocrak (KSNA / Kart Republic) in second. Ironically, the two made contact in a weird circumstances at the end of the session in turn 13. Both suffered mechanical issues, but were back on the grid for their Prefinals. Jarsocrak managed to score the win in the opening Prefinal, holding off championship contender Ryan Norberg (PSL / Birel ART). In the second Prefinal, former SuperNationals winner Jonny Edgar (Tony Kart) grabbed the win over SpringNats victor Dante Yu (CompKart). Maestranzi dropped down the order, placing 16th and forced into the LCQ. Leading the second chance race, Maestranzi suffered an engine failure, and did not transfer. The main event began with Edgar and Jarsocrak on the front row. Norberg and Luke Selliken (RPG / Kosmic) joined them at the front. Selliken moved himself into the lead and looked to have a handle on the race. Jarsocrak and Norberg slipped past him to settle the score. Jarsocrak was able to fend off Norberg in the final corners, scoring his second straight SummerNationals victory. Edgar was able to slip by Norberg for second at the line by four thousandths of a second. Selliken ended up fourth with Alex Bertagnoli (FMS / Kart Republic) in fifth.
