Lest anyone doubt the all-around natural racing talent of 18-year-old Connor Zilisch, the rookie claimed a series best fourth NASCAR Xfinity Series victory on the season in Saturday's rain-shortened BetRivers 200 at the one-mile Dover Motor Speedway in Dover, Del.Zilisch led 77 of the race's 134 laps in his No. 88 JR Motorsports Chevrolet before NASCAR was forced to call the scheduled 200-lap race early because of rain. A pair of Joe Gibbs Racing Toyotas, driven by former NASCAR Cup Series veteran Aric Almirola and Xfinity regular Brandon Jones rounded out the top three.Although he qualified third - three rookies topped the starting grid - Zilisch ran first or second for most of the race, ultimately taking the lead for good on the restart following the Stage 2 break.'We've been showing it lately,'' a smiling Zilisch said when he was informed on pit road the race was official and he was the winner. 'First of all, I hate that we couldn't finish the race the right way. Aric was really fast and was going to give me a run for my money. Props to him for making me work for it.'Still really proud of this JR Motorsports team. ... We capitalized on all fronts, had good pit stops both stages and put ourselves in a position to be in the right spot when the rain fell. Very thankful.'Zilisch's win total is best in the series. And the North Carolina teenager has been so good this summer that that he's now on an eight-race top-five streak that includes three wins and three runner-up finishes for an average finish of 2.25. He's led laps in 15 of the 19 races he's started this season.Even before making his full-time NASCAR debut this season, Zilisch was a multi-race winner in the sports car ranks with huge victories in the biggest races on the schedule - last year's Daytona 24 hour and Sebring 12 hour endurance classics.Not too surprisingly, he immediately proved himself a road-course ace when given the NASCAR Xfinity Series opportunity, winning from pole position in his first series start at historic Watkins Glen International in Watkins Glen, N.Y., last summer.He answered that resoundingly this year as a full-time competitor, hoisting trophies at Circuit of the Americas and Sonoma Raceway, two road courses, but also proving his oval-metal winning at the 2.5-mile Pocono Raceway last month and now adding the one-miler to an increasingly broad resume.Zilisch's effort at Dover's 'Monster Mile' moves him into second place in the championship standings. He sits 56 points behind points leader and JR Motorsports teammate Justin Allgaier, who finished fourth Saturday.Zilisch's best friend, Richard Childress Racing's Jesse Love was fifth at Dover, followed by Ryan Sieg, polesitter Taylor Gray, Sheldon Creed and rookies William Sawalich and Christian Eckes rounding out the top 10.'It's been awesome and I feel like even when we miss a little bit, we're still a top-five car and being able to go the race track and know that in the back of your head has definitely been comforting and confidence inspiring every weekend,'' Zilisch said. 'Gotta keep knocking the door down with wins.'Jeb Burton, who finished 20th, now holds a seven-point advantage on his cousin Harrison Burton for the 12th and final playoff-eligible position in points.The Xfinity Series returns to action next Saturday at the famous Indianapolis Motor Speedway for the Pennzoil 250. NASCAR Cup Series regular Riley Herbst is the defending race winner.
