(CNN) -- Spain's Jorge Lorenzo extended his lead in the world championship standings with a storming victory in the British MotoGP at Silverstone Sunday. The Yamaha rider overhauled reigning world championship Casey Stoner midway through the race and went clear for his 42nd career title. Only a bad mistake with four laps to go might have cost Lorenzo, but he had time to spare to recover and cross the line clear of Stoner whose Honda teammate Dani Pedrosa of Spain finished third. It extended Lorenzo's lead over Australia's Stoner, who has announced he will retire at the end of the season, to 25 points.
