INDIANAPOLIS — Spain's Jorge Lorenzo has won his first Indianapolis MotoGP title, beating San Marino's Alex de Angelis by 9.435 seconds.

Lorenzo was among the fastest riders this weekend, but early mistakes by his two top rivals made things much easier.

Pole winner Dani Pedrosa went too low through into a corner on the fourth lap Sunday, lost his balance and his bike and skidded across the track. The Spaniard finished 10th.

Five laps later, Lorenzo's teammate, Valentino Rossi of Italy, made a similar error. He also went too low through a corner, lost his balance, sliding across the track and into the grass. Rossi later parked in the pits. It's the first time the six-time world champ did not finish a race since Valencia in 2007.
