MIAMI GARDENS: Kimi Antonelli won the Miami Grand Prix on Sunday for his third consecutive Formula 1 victory as the 19-year-old Mercedes drivers continued to show he’s a legitimate championship contender. Antonelli started from the pole but had a slick start on a damp surface at the Miami International Autodrome. Threats of heavy rain led F1 to move up the start of the race by three hours, and there was an early morning heavy thunderstorm with lightning strikes directly over the Hard Rock Stadium, but it had cleared by the time the event began. Still, the first 25 laps were attacked by the drivers as if the rain could return at any moment, and it led to early chaos, even for Antonelli. Charles Leclerc of Ferrari had a spectacular start from third and surged to the lead when Antonelli went wide off course trying to defend.
