Jorge Lorenzo's faultless victory Catalunya came as an unexpected surprise to the Factory Yamaha star, who afterwards admitted: I didn't expect to win.
Lorenzo led from start to finish throughout the 25-lap race to take the honours and close the gap on MotoGP championship rival Dani Pedrosa to seven points.
The defending world champion, who started from third place on the grid despite suffering clutch issues in qualifying, was celebrating his second successive victory and his third win this season.
“A perfect day - to be honest I didn't expect to win, I knew I had some chance but not like in Mugello where I was more convinced we could get the victory,” said Lorenzo.
“It was really difficult physically as it was the hottest race of the year.
“I kept pushing 100% all race because any mistake would have been a disaster.
“I was surprised at the start as I expected to just pass Cal [Crutchlow] but I passed Dani also,” he added.
“I took profit from it and tried to open the gap but it was not enough to go away, Dani was there and we played some games, I was 0.5 ahead then 0.2; I was going then he was recovering me.
“Finally, because I was tough mentally and never gave up, I could open in the last five laps a little gap that was enough to win.”
Lorenzo was joined on the rostrum by Anna Vives, who designed his helmet for the race and praised Ms Vives for her creativity.
“The girl who designed my helmet, Anna Vives, is famous in Spain; she is a symbol that people with Down syndrome are capable of a lot more than some people think,” he said.
“I think it was very original and colourful so I was very proud and happy to have her on the podium to share the win with me.”Don't miss out!
