Toyota Racing exec to Brad Keselowski: Keep ‘your mouth shut’ about Kyle Busch

Kyle Busch wasn’t in a great mood after finishing second in Sunday night’s Coca-Cola 600 at Charlotte Motor Speedway.

Busch’s frustration was understandable; the Toyotas of Joe Gibbs Racing and Furniture Row Racing dominated the marathon race, but Austin Dillon won by gambling on fuel mileage, leading only the final two laps to win over Busch and Martin Truex Jr.

That prompted an interesting discussion on Twitter involving long-time Busch rival Brad Keselowski and Andy Graves, the group vice president, technical director at TRD, U.S.A., Toyota’s racing arm.
