Lorenzo makes winning start to title defence
Teammate Rossi returns to the podium with second place in Qatar

Spain's Jorge Lorenzo began his MotoGP title defence in style with an emphatic win in the season-opener at Qatar's Losail International Circuit.
The Yamaha ace charged to the 24th win of his MotoGP career, finishing 5.990 seconds ahead of teammate and seven-time MotoGP champion Valentino Rossi.
MotoGP rookie Marc Marquez, of Honda, took a superb third on his debut in the top division under floodlights.
Pole-sitter Lorenzo held the lead right from the start and held on until the chequered flag while the rest of the field behind him traded places.
"I knew it was going to be complicated. I'm happy that Valentino came back in second place, it's good for Yamaha," Lorenzo said.
Rossi, who had had an ordinary weekend going into the race, came into his own in the final stages, going past Honda riders Dani Pedrosa and Marquez in quick succession.
