Lewis Hamilton celebrated the 90th win of his Formula One career, one short of Michael Schumacher’s all-time record, as just 12 cars finished on Sunday's first Tuscan Grand Prix, that was twice stopped and restarted.
Hamilton finished ahead of teammate Valtteri Bottas at Mugello with Red Bull’s Thai driver Alexander Albon in third.
The race was stopped twice after a spate of crashes and three safety car deployments.
The red flag first came out when Alfa Romeo’s Antonio Giovinazzi, McLaren’s Carlos Sainz, Haas’s Kevin Magnussen and Williams’ Nicholas Latifi collided at the end of a safety car period.
Bottas had been leading for Mercedes, with Hamilton second, and controlling the pace.
As the Finn prepared to accelerate away, the back-markers reacted as if the leaders had already restarted.
Sainz hit the back of Giovinazzi’s car as the Alfa swerved.
The safety car was immediately deployed again and the race then halted before a standing restart.
The red flags came out again with 13 laps remaining, and Hamilton leading, when Lance Stroll suffered a puncture and crashed his Racing Point.
Frenchman Pierre Gasly brought out the first safety car after a crash that also took out Red Bull’s Max Verstappen.
