"Luckily, I had a little bit more pace than Marc and I could win this very important victory... because now I'm leading the championship with Valentino," said Lorenzo, the 2010 and 2012 MotoGP champion.

"For Marc, it's now more difficult to recover."

Marquez, who won the last two championships, finished second, 4.462 seconds behind.

Starting third on the grid, Rossi dropped to fifth after the start before quickly rallying to third. Andrea Iannone on a Ducati was fourth followed by Dani Pedrosa, the Honda Repsol teammate of Marquez.

It was the 11th podium in as many races this season for Rossi, the former nine-time champion in all categories.

"Unfortunately, my start was bad and I lost some time in the first laps," Rossi said. "I tried to push but I was not fast and strong enough."

The next race is the British Grand Prix on August 30.
