Spanish teenager Pedro Acosta defied the odds to win the Moto3 race at the Doha Grand Prix on Sunday after starting in the pit lane following a penalty. It was the 16-year-old KTM rider's first world championship victory, having finished second in the season-opening Qatar Grand Prix last week. He beat Darryn Binder into second place and leads the South African by nine points in the early riders' standings. pel-gw/jc/dj
