Ferrari’s Carlos Sainz Jr. won his first pole of the season at the Autódromo Hermanos Rodríguez, and Sergio Perez’s miserable Formula 1 season continued Saturday when he failed to advance out of the first round of qualifying at the Mexico City Grand Prix. “Very happy and great couple of laps, a lot of times around Mexico you always have a feeling you cannot put a lap together and it’s extremely difficult,” Sainz said. Three-time defending champion Max Verstappen, who had an engine change Saturday, qualified second for Red Bull.
