Spieth coughed up six shots in three holes — including a quadruple-bogey seven at the short 12th — to lose a five-stroke lead on the final day and hand England’s Danny Willett the prized green jacket.
Here, Press Association Sport looks at six other on-course disasters which snatched defeat from the jaws of victory.
Tap in a two-foot putt and the green jacket is yours. Easy? Not quite. Hoch’s worst nightmare came true at Augusta in 1989 as he slid the putt wide on the first play-off hole and handed the headline writers a present as his surname rhymed with ‘choke’.
Worse still, Hoch was up against Nick Faldo who, having shot a final seven-under round of 65, sank a 30-footer on the next hole to win the first of his three Masters titles.
Spieth’s blow-out had shades of Norman’s spectacular fall from grace at Augusta in 1996.
Norman blew a six-shot lead by the 11th hole in the final round of the Masters and finished with five bogeys and two double-bogeys for a painful 78. Faldo was lurking again to take advantage and win his third green jacket by five strokes, while Norman was never the same player again.
Van de Velde turned the 1999 Open at Carnoustie into a French farce as he entered the final hole with a three-shot lead.
The engraver had already etched Van de Velde’s name on the Claret Jug as he stood on the 18th but he pushed two shots into rough before sending his third into the Barry Burn.
The Frenchman took his shoes and socks off as he considered playing out of the burn, but he took the penalty and ended up taking triple-bogey and losing a play-off to Paul Lawrie.
Big-hitting Johnson seemed on course for a first Major triumph at Pebble Beach when a third-round 66 put him three shots ahead of Graeme McDowell and five clear of Tiger Woods.
But Johnson suffered a triple-bogey on the second hole and a double on the next. Johnson finished with an awful 11-over par 82 as playing partner McDowell cleaned up.
And five years later the American let slip a two-stroke lead with nine to play for Spieth to capture the title at Chambers Bay.
The 21-year-old had produced rounds of 65, 69, and 70 to take a four-shot lead into the final 18 holes at Augusta. McIlroy seemed in total control of his game but he hooked his tee-shot into a tree at the 10th and found his ball among the cabins.
He ended up making triple-bogey and followed it with a double-bogey on the 12th, his final round 80 leaving him 10 shots adrift of eventual winner Charl Schwartzel.
Four up with four to play in good conditions and it seemed as if Australian Scott was ready to seal the Open deal at Royal Lytham.
But Scott bogeyed the final four holes as his accuracy off the tee and his belly putter deserted him. Scott went into the final round with a four-shot lead over McDowell and Brandt Snedeker, but his 75 saw him drop to second and Ernie Els came out of the pack with a 68 to win his second Claret Jug.
