Andrea Dovizioso came out on top at the San Marino Grand Prix as pole sitter Jorge Lorenzo dramatically crashed with two laps remaining.
Ducati looked set for a one-two with Dovizioso leading Lorenzo, who qualified first with a lap record on Saturday, towards the line, but the Spaniard caved under pressure from future Repsol Honda team-mate Marc Marquez and slid into the gravel at Turn 8.
Cal Crutchlow snatched the final step on the podium as a result of the error from the three-time MotoGP™ champion, who won the previous race in Austria and was on pole for the cancelled British Grand Prix.
Victory sent Dovizioso above Lorenzo and Valentino Rossi, who endured a disappointing return to his home track in Misano, to second place in the riders' standings, but Marquez's advantage at the summit grew by eight points to 67.
WHAT A FEELIN'

The front three were close together until Marquez went down the inside of Lorenzo at Turn 14 with 13 laps to go, and the two Spaniards became preoccupied with their battle.
Dovizioso took full advantage to open up a lead of over two seconds, but his team-mate regained second position and started eating into the gap.
However, Lorenzo was unable to keep the pressure on and handed Marquez's hopes of securing a fifth MotoGP™ title and third in succession a huge boost.
Australia's Jack Miller hoped to be in the podium battle after securing just his second front-row start but he crashed from fourth just three laps in, remounting to finish 18th.
Rossi missed last year's race with a leg injury and his return was not one to remember. He could only guide his Movistar Yamaha to seventh, two positions behind team-mate Maverick Vinales.
