Danilo Petrucci, an Italian riding for local team Ducati, held off Marc Marquez to gain a first ever MotoGP victory on Sunday in the Italian Grand Prix.
The second place allowed Spaniard Marquez to increase his lead in the world championship ahead of another Italian on a Ducati, Andrea Dovizioso, who finished third on Sunday after a prolonged three-way battle.
Five-time MotoGP champion Marquez on a Honda briefly took the lead in the last lap but Petrucci recaptured first place and won.
"It's amazing, I'm thrilled," said 28-year-old Petrucci, who finished eighth in the 2017 and 2018 world championships.
"On front of my home crowd and in my town, it's incredible, I can't describe how I feel."
Marquez -- winner of three out of six races this season -- started on pole but had to battle with the Ducati riders and Suzuki's Alex Rins, who challenged hard despite starting back on the grid.
The four riders overtook each other several times but Petrucci found the power to pull clear on the final lap of the fast Mugello circuit.
Italian star Valentino Rossi crashed out of his home race where the Yamaha rider has not won since 2008 after an impressive series of seven consecutive victories.
