After overpowering Crooked Stick for four straight days, Dustin Johnson has his third win of the season. Here's how things ended up at the BMW Championship, where Dustin Johnson cruised to a three-shot victory:
Leaderboard: Dustin Johnson (-23), Paul Casey (-20), Roberto Castro (-17), Adam Scott (-12), Matt Kuchar (-12), Charl Schwartzel (-12), Ryan Palmer (-12)
What it means: Johnson opened the day with a three-shot lead, but two bogeys over his first three holes allowed Casey to catch up.
