Dominant Dustin Johnson wins BMW Championship to move top of FedEx Cup standings

Overnight leader Dustin Johnson survived an early wobble to win the BMW Championship at Crooked Stick and move top of the FedEx Cup standings with one event to go.

The US Open champion won by three shots, having initially extended his advantage to four at the opening hole only to bogey the next two to find himself in a tie with in-form Englishman Paul Casey.
