Lorenzo and Rossi both crash out - but world champion finishes fifth
Honda's Andrea Dovizioso scored a surprise win in the British MotoGP at Donington Park after a chaotic race which saw three race leaders crash out.
Two such were Fiat Yamaha duo Valentino Rossi and Jorge Lorenzo - the former able to remount his bike and finish fifth.
With Lorenzo unable to do the same, defending world champion Rossi has therefore increased his lead over his team-mate in the standings to 25 points.
Even so, the defending champion will surely rue throwing away a gilt-edged chance to place a stranglehold on another title.
Ducati's Casey Stoner also had an afternoon to forget, the 2007 world champion's tyre gamble backfiring to leave him down in 14th place.
Rain showers which had plagued the Leicestershire track all weekend prompted Casey's decision to start with wet tyres on a dry track, with team-mate Nicky Hayden following suit.
However, the rain held off until light showers near the end and Stoner soon found himself at the back of the field.
Setting the tone for the afternoon was the sight of Toni Elias - who qualified eighth - leading the race for the first two laps.
Lorenzo took the lead before Elias suffered a high speed crash when he highsided after drifting on to the wet kerbs at Starkey's Bridge
The unpredictability increased when Lorenzo crashed out on lap eight after losing the front end at Goddards - the young Spaniard retiring after frantic efforts to retrieve his bike.
And it moved on to a whole new level when Rossi, who appeared set for a routine win after inheriting the lead, then crashed at the Foggy Esses.
Dovizioso was on hand to pick up the pieces and score his maiden win ahead of Colin Edwards and Randy De Puniet.
Alex De Angelis was fourth with Britain's James Toseland set for a career best fifth until Rossi somehow clawed his way back past him on the final lap.
Earlier, British rider Scott Redding - winner last year - finished third behind Julian Simon in the FIM 125cc World Championship race.
