Jordan Spieth admitted he would probably sleep in the green jacket after claiming his first major title in record-breaking fashion in the 79th Masters on Sunday.

Spieth became the first player ever to reach 19 under par at Augusta and only a bogey on the 18th prevented him from adding the 72-hole scoring record to the 36 and 54-hole records he set on Friday and Saturday.

The 21-year-old also became the second youngest champion behind Tiger Woods — whose 18-under total he equalled — after a closing 70 left him four shots ahead of Justin Rose and Phil Mickelson.

“I plan on not taking it off for a while,” Spieth said after being presented with the green jacket by 2014 winner Bubba Watson. “I’ll probably sleep in it for a few nights.

“It’s the most incredible week of my life. This is as great as it gets in our sport. It’s a dream come true for me. I did not break 70 last year even having a chance to win so to shoot some low scores and hear those roars is very special.

“To join the club that is the green jackets and to join Masters history and put my name on that trophy and to have this jacket forever, it’s something that I can’t fathom right now.
