FONTANA, Calif. (AP) — Kyle Larson hopes his NASCAR Xfinity race victory will catapult him to a weekend sweep at Fontana. The way this season is going for the overall Cup series points leader, it's tough to argue against it. Larson held off Joey Logano on the final lap to win another Xfinity race dominated by Cup drivers on Saturday. Larson thrived out of a late restart with smart moves and a clever lane choice on Fontana's five-wide asphalt.
