Jordan Spieth must have been having flashbacks to the 2016 Masters during the final round of The Open.
A year ago at Augusta, Spieth looked in imperious form going into the back nine on Sunday.
However, with a five shot lead with just nine holes to go, the defending champion suffered one of the most spectacular collapses in Major Championship history.
Back-to-back bogeys at 10 and 11, combined with an ugly quadruple-bogey at 12, effectively put an end to his hopes and he would finish three shots behind eventual winner, Danny Willett.
Last week at The Open, the American had built a commanding lead at the top of the leaderboard going into the final day at Royal Birkdale.
However, in fashion reminiscent of his collapse at Augusta, a disastrous front nine left Spieth's hopes of winning his first British Open title hanging by a thread.
And his poor play was compounded by a bizarre drive at 13, whereby the Texan blocked his drive way right.
When Spieth was forced to drop his ball back in the driving range, it looked as if there would be no way back as Matt Kuchar looked in pole position to take his maiden major title.
His tee-shot was so far wide of the mark, that Spieth's caddie, Michael Greller, was forced to guess the yardage of which the American was to the pin.
Greller, who is also responsible for the penning and completion of Spieth's scoring notes for the round, wrote in reference to that second shot on 13: "Practice range shot: No number (yardage), we guessed 240 yards."
But the world number three was not fazed by his error and he would miraculously recover from his horrific drive; eventually holing a clutch eight-foot putt to secure a morale boosting bogey.
This miraculous recovery actually worked in Spieth's favour as he bounced back superbly to gain an incredible six shots in the next five holes, ensuring he would win the Claret Jug for the first time.
That means the American has now won at three of the four golfing majors, and he will now attempt to complete a career grand slam at the PGA Championship next month.
If he were to emerge victorious at Quail Hollow, Spieth will undoubtedly be hoping that the win will be much more straight forward than the rollercoaster ride of emotions he was made to endure at Royal Birkdale.
