Monza - French driver Romain Grosjean was disqualified from the Italian Grand Prix on Sunday after stewards upheld a Renault protest against the legality of his Haas car.
Grosjean had finished sixth in the race, sending Haas ahead of Renault in the constructors standings.
The disqualification, which is subject to appeal, meant the French carmaker stayed fourth while Force India's Esteban Ocon was promoted to sixth in the race.
Force India's Sergio Perez moved up to seventh, with Renault's Carlos Sainz eighth and the Williams pairing of Lance Stroll and Sergey Sirotkin ninth and 10th.
The point was Sirotkin's first in Formula One.
