DOVER, Del. — Fox Sports NASCAR pit reporter Amanda Busick said pit crew member Donovan Williams “saved my life” Friday at Dover Motor Speedway after a frightening runaway pit cart incident.After the NASCAR Truck Series qualifier at Dover, Busick was walking along the back of pit road when a runaway pit cart weighing approximately 4,000 pounds barreled down a hill directly toward her. Williams reacted quickly and jumped in front of Busick to shield her, putting his body between her and the cart as they hit the ground.Williams, a Hendrick Motorsports pit crew member and former UConn football player who was working as a tire changer for Spire Motorsports’ Truck team Friday, bore the brunt of the impact and was hospitalized with minor injuries.“You see it all happening in slow motion, but super-fast,” Busick told The Athletic. “I could see the cart coming; I could see, who I now know is Donovan Williams, trying to brace the cart, but it just had so much speed. There was no way that he could keep up with it.“This all happened in probably less than half a second, maybe a second. And Donovan, in his attempt to shield me, we kind of got collected and then would have been pushed, I don’t know, I’d say probably five to 10 feet together with the cart behind him and him on me.“That guy saved my life.”
