Max Verstappen says committing to a two-stop strategy for the Mexican Grand Prix was an overly conservative approach but was satisfied with his Toro Rosso's race pace to claim his ninth top ten finish of the year.
The Toro Rosso driver produced a solid but unspectacular race at the Autodromo Hermanos Rodriguez and felt despite having the speed to match the cars in front of him his race was slightly compromised by stopping twice when he could have pushed for a more aggressive tyre strategy.
“We were quite quick, quite fast, especially in the first two stints of the race,” Verstappen said. “We decided to go to a two stop and immediately I saw that the one stop was the right option probably but we'd committed to a two stop.
“We were quite fast on track, saving a lot of brakes and the engine, without pushing at all during the whole race until the last stint where we put on another set of soft tyres and all of sudden, I don't know why, we lost like two seconds per lap.
“We managed to pass a Force India, we managed to undercut Perez. I was really quick at the beginning and the middle part of the race until the safety car; then after the safety car we suddenly lost two seconds of performance.”
Despite his frustrations, the rookie secured another points finish - his ninth of 2015 - to strengthen his position in the top ten of the F1 Drivers' Championship.
Verstappen has already outscored Daniel Ricciardo and Jean-Eric Vergne in their debut F1 seasons with Toro Rosso and currently holds tenth in the standings, two points ahead of Romain Grosjean.
