MARTINSVILLE, Va. — Noah Gragson celebrated his first trucks win by impersonating Helio Castroneves and climbing the fence at Martinsville Speedway. Then he went a step further Saturday and did pull-ups while dangling from the fence. It was a bit too much for the 19-year-old as he vomited over the side of the racetrack wall after his climb.Gragson passed two-time champ Matt Crafton on the final restart to win the Texas Roadhouse 200, becoming the 10th first-time truck series winner at Martinsville. Gragson had other gaffes. He referred to Martinsville's signature grandfather clock trophy as a "granddaddy watch," then struggled later to discuss the historic piece. "What the hell do you do with that thing, honestly? They don't teach kids anymore how to tell time like that," he said. Gragson, who is from Las Vegas, won for Kyle Busch Motorsports. Busch, who also is from Las Vegas, uses the team to groom young talent.F1: Lewis Hamilton will be chasing his fourth series championship from behind Sebastian Vettel. At least from the start of today's Mexican Grand Prix. Blistering late laps by Vettel and Max Verstappen in qualifying has Ferrari and Red Bull starting 1-2 at the Mexico City race. Hamilton is starting third. Hamilton leads Vettel by 66 points in the race for the championship with three races left and can win it today if he finishes fifth or better.
