Dustin Johnson finally wins Masters with record low score

Dustin Johnson finally clinched an elusive second major title with a five-stroke victory at the Masters on Sunday, staving off self-doubt as he overcame a shaky start to his final round to end with a tournament-record low score at Augusta National.

American Johnson led throughout, though only by one stroke early, and did not drop a shot in the final 13 holes on his way to a four-under-par 68 and an unprecedented 20-under-par 268 total.

Australian Cameron Smith and South Korean Im Sung-jae kept Johnson honest after starting four shots back.
