(CNN) -- Spain's Jorge Lorenzo was crowned MotoGP world champion Sunday after finishing second behind home favorite Casey Stoner in the Australian round at Phillip Island. The Yamaha star took full advantage of a mistake by his closest rival Dani Pedrosa, who came off on Turn Four of the first lap to see his title hopes disappear. Pedrosa's Honda teammate Stoner rode a peerless race to secure his sixth straight win on his home track, a fitting finale before his retirement at the end of the season. Lorenzo held off Britain's Cal Crutchlow (Monster Yamaha Tech 3) to clinch his second world title in motorcycling's premier class.
