Charles Leclerc dodged a team order by passing his number 1 teammate Sebastian Vettel in Bahrain.
Just before mounting the overtake of the sister Ferrari, the 21-year-old dubbed "golden boy" by the Italian press said on the radio: "Guys, I'm quicker".
His engineer replied that he should wait at least two laps.
"Then on the next straight I had the opportunity to go for it, so I went for it," said Monaco-born Leclerc.
"It's always a tricky situation when you fight your teammate because the risks are very high," he said.
"They warn you before the race to please be careful with your teammate, but I had the opportunity and I didn't hesitate."
