Rory McIlroy would already have secured his place in golf's Grand Slam club had it not been for his final-round collapse at Augusta five years ago.
The then 21-year-old had shared the first round advantage thanks to a seven-under 65 and found himself armed with a four-shot lead on Saturday after maintaining his impressive start to the week.
Bogeying the par-four first on Sunday was a sign of things to come for the Northern Irishman, who reached the turn clinging on to a one-stroke advantage but saw his chances of victory unravel over the space of four holes.
A triple-bogey at the 10th was followed by a three-putt bogey from less than 10 feet at the next, before taking four putts to double-bogey the 12th.
McIlroy's misery worsened when he yanked his drive at 13 in to Rae's Creek, eventually closing an eight-over 80 as Charl Schwartzel took the Green Jacket.
"It all went a bit pear-shaped," was how McIlroy summed up his Sunday afternoon nightmare. He wasn't wrong.
