Britain's Lewis Hamilton won the Italian Formula One Grand Prix for McLaren on Sunday with Sauber's Mexican driver Sergio Perez finishing second.
Red Bull's world champion Sebastian Vettel, who had been Alonso's closest rival in the standings before the start, retired six laps from the finish. McLaren's Jenson Button, winner in Belgium last weekend, also failed to finish.
