Reigning MotoGP champion Francesco Bagnaia has won the Italian Grand Prix in style at the Mugello Circuit, while teammate Enea Bastianini overtook Pramac Racing's Jorge Martin on the last turn of the final lap to take second place.

Australia's Red Bull KTM rider Jack Miller had to be content with 16th, a result that leaves him in the same place in the overall standings, one down on his position going into the weekend.

Miller, who has struggled in the second year of his two-year deal with KTM, reportedly admitted on Friday that he would accept being moved to Red Bull's Tech3-badged Gas Gas team in 2025, aware and understanding that Pedro Acosta is a prime candidate to take his ride.

Ditching Ducati's traditional red livery for the Italian 'Azzurri' blue on their home circuit, Bagnaia was a man on a mission to seal the sprint and race double at Mugello as he closed the gap on championship leader Martin.

The world champion, now 18 points behind Martin, celebrated his victory by strumming an imaginary guitar before he was handed an electric guitar by the fans to go with his helmet and racing suit inspired by the rock band Kiss.

A sprint winner on Saturday, Bagnaia had been demoted to the second row due to a three-place grid penalty from Friday's practice which allowed Marc Marquez, fourth-fastest in qualifying, to start on the front row.

But Bagnaia could not have dreamed of a better start as he overtook four riders and raced into the lead on the opening lap, drawing a huge roar from the Ducati fans in the stands as Bastianini also slotted into third place.

"It wasn't easy starting from P5 but I had a strategy to go on the outside," Bagnaia said. "To win today after a week like this is fantastic."

Marquez found overtaking Bastianini difficult while the Spaniard also had to look over his shoulder with Tech3's Pedro Acosta hot on his heels and waiting for the six-time MotoGP champion to make a mistake.

There was less than a second's gap in each battle for the top four spots but overtaking attempts were difficult to come by for the riders on the fast circuit until the final stages of the race.
