Bryson DeChambeau is confident he can still claim a stunning victory at the Masters, after threatening to claim the lead from playing partner Jordan Spieth prior to a late collapse on day two.
The 22-year-old amateur - who is set to turn professional next week - produced a stunning display in tough conditions to reach four under through 15 holes of his second round at Augusta.
On a day when no player broke 70, DeChambeau was cruelly denied the stand-out score when he ran up a triple-bogey seven at the 18th - courtesy of two pulled tee shots - to slip back to even par for the tournament.
While naturally disappointed with his efforts at the last, which saw him fall four shots behind Spieth with two rounds to play, DeChambeau retained a positive outlook.
"It's not a score you want on the last hole but I just hit a couple of bad drives and that's what led up to it," he told Sky Sports.
"I just unfortunately messed up at the last, but you know what, it's golf - I'm not worried about it.
"It was awesome [to play alongside Spieth]. I've always enjoyed Jordan's company and I enjoyed it thoroughly out there with him. I learned a lot and it was quite fun.
"It's impossible to know how much this experience is going to help. I think going forward it will definitely help me, I just don't know how much."
Asked if he believed he could still win the tournament, a confident DeChambeau said: "There's no doubt."
