Australia’s Jack Miller has won his second successive Moto3 race of the season with a triumph at the Grand Prix of the Americas.

The 19-year-old, who captured his maiden race victory in Qatar last month, had started on pole on his KTM on Sunday.

He then survived a series of challenges from Romano Fenati, who was second, and Efren Vazquez, on the last two laps to secure victory.

“I felt strong on the brakes. That’s always been one of my strong points, maybe too strong as it can kill the exit speed,” said Queensland native Miller.

“But here it works really well. I’m stoked to have won, I led every lap.”
