Dani Pedrosa obliterated the opposition for his first MotoGP victory of 2010 at Mugello on Sunday.
Pedrosa's Honda rocketed away from pole position and never looked back, as closest challenger Jorge Lorenzo, who had won the last two races for Yamaha, had no answer to his pace.
Pedrosa repeatedly smashed the lap record, lapping close to his qualifying speed, to extend a 7.8sec lead, after which he backed off to a 4sec victory at the finish.
Lorenzo was caught up in the early stages with Pedrosa's Honda teammate Andrea Dovizioso, who powered past him at Turn 1 at the start of lap four. Lorenzo got him back at the same place two laps later and managed to keep him at bay for the rest of the race.
A sensational battle for fourth place was won by Casey Stoner's Ducati. After a big moment at Turn 1 on lap 13, he sat back and watched Marco Melandri and Randy de Puniet swap the position before putting the hammer down on the final lap and jumping past both of them. Melandri didn't lie down, however, and repassed Stoner before the Aussie got him back with a couple of corners remaining. Stoner crossed the line just 0.032sec ahead of the Gresini Honda man, who had started down in 14th place.
Behind de Puniet's LCR Honda was the top Tech 3 Yamaha of Ben Spies, who finished well clear of Aleix Espargaro (Pramac Ducati), Marco Simoncelli (who went off on the opening lap on his Gresini Honda) and a disappointed Loris Capirossi (Suzuki).
Nicky Hayden was the race's biggest casualty when he crashed out on lap six while embroiled in battle with Melandri over fifth.
"I blew the start, but picked a few guys off," said Hayden. "But coming into a downhill corner, where I was making up time, I pushed too hard. That one's on me, rider error. The setup wasn't great, so I was just trying to ride through it."
Lorenzo now leads the standings by 25 points over Pedrosa, who gained five points on the title favorite. Injured Valentino Rossi remains third, just three points ahead of Dovizioso.
