Dustin Johnson knows as well as anyone that no matter how good he is and how well he plays, something can always go wrong in golf.
Just not this week at the BMW Championship.
Not this year, really.
An awesome talent, Johnson is starting to pile up the victories to prove it. He ran off four birdies in a five-hole stretch to regain control Sunday, left Paul Casey feeling helpless by matching his eagle putt late in the round and sailed home to a 5-under 67 for a three-shot victory at Crooked Stick.
