After several near-misses in recent years, Johnson finally clinched his first major title amid high drama as he was forced to negotiate the final seven holes under notice that he might be penalised for a rules infraction.
He also held top spot on the FedExCup points list going into the season-ending Tour Championship, where he narrowly missed out on the mind-boggling $10 million playoff bonus after struggling to a closing 73.
