Jorge Lorenzo dominated his home Grand Prix in Catalunya, even beating Dani Pedrosa to the first corner. After qualifying 3rd, Lorenzo led from start to finish, with relatively little pressure put on him. Pedrosa though, was more worried by team mate Marc Marquez as the race went on, as the rookie looked to have the faster pace, cumulating in an attempted lunge down the inside of Pedrosa on the penultimate lap which almost saw Marquez lose control. Valentino Rossi rode a lonely race in 4th, after Cal Crutchlow, who was bidding for a 3rd successive podium, crashed on lap 6. Stefan Bradl finished 5th, with Bradley Smith pipping Andrea Dovizioso to 6th, his highest finish so far in his rookie season. Aleix Espargaro finished top CRT in a career best 8th, with Colin Edwards recording an impressive 9th. After crashing early on, Michele Pirro, standing in for Ben Spies, got back on to finish 10th.
Crutchlow was one of many riders not to finish, with no fewer than 8 riders failing to finish. Alvaro Bautista, who almost took out Rossi in his crash, and Michael Laverty crashed out early on, with Hector Barbera, Nicky Hayden, Andrea Iannone and Randy De Puniet also crashing, with Karel Abraham retiring.
Lorenzo’s win moves him just 7 points behind Pedrosa in the championship, with Crutchlow holding on to 4th place despite his crash.
Pol Espargaro won the Moto2 race, with championship leader Scott Redding finishing 4th, and Luis Salom won the Moto3 race.
