Lorenzo rides to first victory of 2010 at Jerez
A rapid start to the race saw pole holder Pedrosa lead into Turn1, with Rossi rising from fourth on the grid to follow the Spaniard and Hayden also shooting up from the second row as the riders all battled for early positions.
On the third lap Loris Capirossi (Rizla Suzuki) crashed out and shortly after Aleix Espargar¢ also fell. The Pramac Racing rider managed to return to the track however, but Capirossi’s race was finished, and on lap eight Ben Spies (Monster Yamaha Tech3) pitted and retired with a front tire problem on his M1 machine when competing inside the top ten.
As the midway point of the race approached Pedrosa was leading well at a second-and-a-half ahead of Rossi, with Lorenzo a further two seconds back. The fight for seventh place was a close one, with San Carlo Honda Gresini team-mates Marco Melandri and Marco Simoncelli battling one another amongst a group of five riders.
At the same time Lorenzo was closing the gap on Rossi and on lap 21 passed his team-mate, and turned his focus to hunting down Pedrosa. From there a superb duel developed between the two Spaniards.
With two laps to go Lorenzo caught up with the factory Honda rider and made his move to pass, but Pedrosa held his line and the two almost touched as the excitement continued to increase.
And so it came down to the last lap and as Pedrosa pushed it wide at the Dry Sack corner Lorenzo swept through to assume the lead, which he held to ensure he received his reward for a fantastic ride. Crossing the line the Fiat Yamaha rider was 0.543s ahead of Pedrosa, with Rossi placing third to complete the podium.
Completing the top five were Ducati Marlboro riders Nicky Hayden, who repeated his fourth spot from Qatar, and Casey Stoner, with Andrea Dovizioso taking sixth place.
Mika Kallio (Pramac Racing) completed an impressive rise from last place on the grid to take seventh, with Melandri, Randy de Puniet (LCR Honda) and �lvaro Bautista (Rizla Suzuki) also placing inside the top ten.
Jorge Lorenzo – Position: 1stTime: 45'17.538
"It has always been one of my dreams to win a MotoGP race in Spain and this was like a movie, everything that could possibly happen did! It was a very hard race because I made such a bad start and then found it very difficult in the first laps – I gave myself a tough job to do. After that I started to feel better and rode like a demon to get to the front. Once I passed Valentino I knew that I couldn't take it easy, I had to try everything to win and it was all I could think about. I had a great fight with Dani and in one moment we nearly crashed so I had to try again, on the very last lap! I know it's better to win races calmly, from the front, but lately that hasn't been the way for us and I have had to fight on every lap. I saw the lake on Thursday and thought it would be funny to jump in and I think the fans liked it, but I didn't really think about how heavy I'd be with wet leathers and for a minute I thought I wasn't going to get out! This has been an amazing day, I can't believe I've achieved this dream of mine, in front of all the Spanish fans at this magical place."
