The week in Las Vegas motor sports

Las Vegas Motor Speedway is adding another loge seating area for the inaugural South Point 400 NASCAR weekend in September. The premium seating boxes in Turn 4 will mirror the ones in Turn 1. The loge will include swivel armchairs, padded seating, food-and-beverage stations, wait-staff service and rails upon which to place drinks. Riley Herbst made another successful debut in a major NASCAR series, finishing eighth in a Truck Series race at Gateway Motorsports Park near St. Louis. Fellow Las Vegas youngster Noah Gragson led a race-high 63 laps before fading to 10th at the finish due to a tire problem. The racing world continue to mourn World of Outlaws driver Jason Johnson, who was killed in a crash in Wisconsin. Johnson was a regular competitor at The Dirt Track at Las Vegas Motor Speedway.
