Jordan Spieth was left to rue a "lack of discipline" as he saw the chance to defend his Masters title slip by on a dramatic Sunday at Augusta.
Spieth started the day with a one-shot lead over Smylie Kaufman but after a blistering run of four consecutive birdies to close out the front nine he blew up spectacularly around Amen Corner as Danny Willett claimed a maiden major title.
Despite fighting back with birdies on 13 and 15, a bogey at the par four 17th ended his challenge and left Spieth with a second runners-up finish at Augusta either side of his victory last year.
After bogies at 10 and 11, the American recorded a quadruple bogey seven on the 12th, finding the water twice and left him playing catch-up and it was that hole he was left to rue.
"It's tough, it is really tough," Spieth told CBS. "That ball flight is one that has come up a lot this week on par threes. I'm not getting around my body enough and I put a bad swing on it at the wrong time
"I probably should have gone to the drop zone where we knew the yardage. It was tough to commit over by the 13th hole.
"It was a lack of discipline to hit it over that bunker coming off of two bogeys instead of recognising that I'm still leading the Masters by a couple of shots.
"Four birdies in a row to end the front nine I knew that even par was good at least by a shot and sometimes that makes it hard - you go away from the gameplan that I was using on the front nice and you go a bit conservative."
When asked how he will reflect on events, despite overall another impressive showing at a major, the 22-year-old was quick to respond: "I'm pretty sure I will be disappointed.
"We still have the confidence that we are a closing team, I have no doubt about that ability - it was a very tough 30 minutes that hopefully I never experience again."
