Teen sensation Connor Zilisch raced to a win in his NASCAR Xfinity Series debut, saving enough fuel in a wreck-marred finish to take the first of what many in the industry expect to be many checkered flags on Saturday at Watkins Glen International. Zilisch, who turned 18 in July, spent the majority of the race leading in the No. 88 Chevrolet for JR Motorsports and was nowhere near the chaos in the back of the pack, but he was forced to stretch his fuel. “I’ve worked so hard for this one,” Zilisch said.
