The Masters: Green jacket's a bit big for my son but I'm sure he'll grow into it, says Danny Willett after Augusta triumph

Willett’s wife Nicole had been due to give birth to the couple’s first child on Sunday, but Zachariah James Willett arrived early to allow his proud new father to play in the year’s first major.

The 28-year-old was the 89th and final player to register after only arriving at Augusta on Monday, but took advantage of a dramatic collapse from defending champion Jordan Spieth, who presented Willett with the famous green jacket.

“On this rare occasion I’m nearly speechless,” Willett said at the presentation ceremony. “It’s been a fantastic week on and off the golf course.

“My wife gave birth last Tuesday, which allowed me to come here and it’s been one of those crazy weeks where things seem to go your way. The 80th Masters is always going to be special and dear to my heart.

“My wife was born 28 years ago (on Monday) and my son was due today and he came early to let me come and play. You talk about fate and everything that comes with it.... it’s been crazy.

“People were saying, ‘try to bring the green jacket home for the little man’. It’s a bit big, but I am sure he will grow into it.”

Spieth had birdied four holes in a row from the sixth to reach the turn with a five-shot lead and seemingly guarantee he would join Jack Nicklaus, Nick Faldo and Tiger Woods in winning back-to-back Masters titles.

However, the world No 2 - who had led for seven rounds in succession following his wire-to-wire victory last year - then dropped shots at the 10th and 11th and ran up a quadruple-bogey seven on the 12th after hitting two balls into Rae’s Creek in front of the green.

Playing three groups ahead, Willett had birdied the 13th and 14th to reach the top of the leaderboard and another on the 16th helped complete a superb 67.

And although Spieth kept his hopes alive with birdies on the 13th and 15th, a bogey on the 17th meant Willett could celebrate becoming the first English winner since Faldo in 1996 and the first European since 1999.

“You can’t really describe the emotions and feelings,” added Willett, who finished three ahead of playing partner Lee Westwood and Spieth. “We all try to play good golf and someone has to win and fortunately today it was my day.

“Every time we seemed to make ground, Jordan kept pulling ahead. We kept trying to dig in. I thought we had to get to seven under and we looked up and Jordan was already seven. It was a very surreal day when you look back at the ebbs and flows.”
