50. Arnold Palmer wins again, 1960
Winning his first Masters in 1958, Palmer started the 1960 edition with a 67 and held the lead at the end of each round. On the last day, Ken Venturi edged in front, but Palmer wasn't done. He birdied the 17th to level and the 18th to beat Venturi by a stroke. Palmer's stellar career includes winning 23 times on the PGA Tour between 1960 and 1963.

49. Billy Casper shoots 106, 2005
Billy Casper, the 1970 champion, had an embarrassing time at Augusta in 2005. He lost five balls in the water on the way to a 14 at the par-three 16th, and dropped 34 strokes in all during a round of 106, the highest in Masters history. But Casper's score doesn't show up in the record books: he declined to hand in his scorecard afterwards and was disqualified.

48. Mike Weir is the first left-hander to win, 2003
No left-handed golfer had ever won the Masters before Mike Weir took the green jacket at Augusta in 2003. He managed a bogey-free 68 on the final day which put him into a play-off with Len Mattiace. Weir became the first Canadian to win a major after out-fumbling Mattiace to triumph with a bogey at the first play-off hole, the 10th.

47. Art Wall birdies the last to win, 1959
After losing a two-shot lead to the 1955 champion Cary Middlecoff at the 15th, Art Wall calmly continued a sequence of five birdies in the last six holes. His 12-foot putt on the 18th green was his fifth birdie and what turned out to be a one-shot victory. Wall claimed to have managed more than 40 holes-in-one in his life.

46. Ben Hogan three-putts the 18th, 1946
Missing out on a play-off in 1942, Ben Hogan was set to win his first Masters four years later when long-time leader Herman Keiser three-putted at the last. Having taken a five-shot lead into the final round, Keiser was exhausted having led since the first day. He recalled that as he waited for Hogan to play the 18th, "I hoped he'd make either a birdie three to win or a five to lose ... I didn't want any play-off." Hogan obliged and, with victory in sight, three-putted to lose by one.
