Max Verstappen believes a "calm" opening stint, coupled with strong pace on Hard tyres, were the key factors behind his Formula 1 race win in Miami.
With Verstappen starting in P9 on the Hard tyres and switching to Mediums for the final stint, the Red Bull driver ran an opposite strategy to teammate Sergio Perez, who started on the Mediums.
The reigning World Champion took advantage of the fresher tyres to pass Perez with ten laps to go and secure the victory.
Speaking after the race, Verstappen explained that the confidence to go longer on the Hard tyres made the difference in the Miami race.
"It was a good race. I stayed out of trouble in the beginning, and then just had a clean race," Verstappen told media.
"I picked the cars off one by one, and then I could stay out really long on the Hard tyres, and that's where I think we made the difference today, and then had a good little battle with Checo at the end.
"We kept it clean and that's most important.
"Yesterday was of course a bit of a setback, but today we just kept it calm, and kept clean. Winning a race from P9 is always very satisfying!
"We didn't know what the weather would do, but we were quite confident that this [strategy] would pay off. Luckily it did today."
