LONG POND, Pa. (AP) — Dale Earnhardt Jr. won his NASCAR national series debut as a crew chief in Saturday’s Xfinity Series at Pocono Raceway. Pressed into unexpected service, Earnhardt called the shots for 18-year-old prospect Connor Zilisch in the No. 88 Chevrolet and they both landed in victory lane. Earnhardt made a pit stop from his day job as team owner at JR Motorsports with normal crew chief Mardy Lindley suspended one race because of a lug nut infraction earlier this month at Nashville.
