I'm going to say goodnight now. Until we meet again in June, adieu, and there will follow messages from various golfers and BBC crew in Augusta. Night.

Phil Mickelson, reflecting on his 14 under: "I played just a good, solid round of golf, but I needed something exceptional today. I needed to shoot something in the mid to low 60s to get a chance. It was a fun tournament. I thought I played some great golf but I just got outplayed. I would have taken 14 under at the start of the week and thought that would have won it."

Mickelson on Jordan Spieth: "He's obviously a tremendous player but he's a tremendous individual, too. It's hard not to like, hard not to pull for the guy."

"Spieth has so many attributes, he has the temperament, skill, temper, lifestyle. Everything appears to be working in a wonderfully clear direction."

Jay Townsend
Former American professional golfer on BBC Radio 5 live

"This is a great story for American golf as we've been taking a beating. It was such an amazing performance. Greatness is something I don't use very often, in fact I think it gets overused. But I think this kid has the chance to become great.

"I think golf's in great shape. We have a young superstar in Spieth from the US, McIlroy from Europe, Matsuyama from Asia. It's been a long time, not since Tiger was coming up do I think golf's been in such a strong position."

How does it fit Jordan?

Tributes to Justin Rose, England's former US Open champion gave it bunches this week. He's building a reputation as one of Britain's greatest golfers, and that was his third top-10 finish at Augusta and ninth in majors. World number two Henrik Stenson was one of only two players without a three-putt at Augusta this year, the other being South Korea's Sangmoon Bae.

Masters champion Jordan Spieth gives his views in the Butler Cabin: "It was very nerve-wracking today. I thought today might be a little easier than yesterday. I didn't sleep well last night... and with two major champions behind I couldn't let up. It's the most incredible week of my life, this is as great as it gets in our sport. This is a dream come true for me.

"To shoot some low rounds, make some putts, and hear those roars, it was remarkable. I saw my family and friends right behind the green on the 18th and at that point knew it was going to be a done deal, it didn't kick in there, it still hasn't kicked in. I'm still in shock a little bit.

"I want to be like Bubba. I want to win two Masters. I know being the reigning Masters champion is going to carry a weight with it, I'm sure I'll figure it out in the next year."

The Butler Cabin looks like the study of a reclusive tycoon, who has not had it redecorated since 1962. But great things happen within its walls. Defending champion Bubba Watson and new champion Jordan Spieth sit before Jim Nantz and Augusta National chairman Billy Payne, looking like a couple of school prefects being debriefed by the headmaster and his deputy. And on goes the jacket! Got a little bit snagged on the sleeves, I've seen better.

In 1960, a television interview with tournament co-founder Clifford Roberts and the new champion became a staple of the broadcast.

And here comes the latest one...

Sergio Garcia: AWESOME @JordanSpieth! Very much deserved 1st mayor! Great player and great guy!

Brooks Koepka: Congrats to my buddy @JordanSpieth on the win! Unbelievable play this week and well deserved win!

Graham DeLaet: What a player that kid is.

Luke Donald: Amazing performance from a great kid, congrats @JordanSpieth #MastersChamp

It's not as if they didn't go low behind him, there were a couple of 66s, but somebody really needed a 64 or 63 to make it properly interesting. And so, to the Butler Cabin, where Jordan Spieth, for all his monumental efforts, will be presented with a blazer that looks like it's spent too long in the window of a provincial gentlemen's clothes shop.

"Jordan Spieth's Mum and Dad told him to go and thank the patrons first. Also, they shook the hand of Justin Rose first before congratulating their son. Classy. I just love that Spieth, the new Masters champion, still does what Mum and Dad tell him."

It is four days in the making but here is how the 2015 masters leaderboard finished up:

The Masters has five men who have won wire-to-wire (golf speak for day one to four).

Craig Wood, 1941

Arnold Palmer, 1960

Jack Nicklaus, 1972

Raymond Floyd, 1976

And... Jordan Spieth 2015.

Off Spieth goes to the scorer's hut, which is less of a scorer's hut and more like the sort of gaff Scarlett O'Hara lived in. Spieth is the second-youngest Masters winner, after Tiger Woods in 1997. It's great to have an injection of youth in the game again - could this be the start of the McIlroy-Spieth era?

Ken Brown
BBC Sport commentator

"Anyone in the world would say well played, it was a fantastic performance from start to finish. He was under severe pressure at the weekend but got it under control and we are looking at a new superstar, his golf was brilliant."

Peter Alliss
BBC Sport commentator

"These are the most joyous scenes I have ever scene at Augusta, so many young people that is the lovely thing to see."

Iain Carter
BBC golf correspondent on Radio 5 live

"Golf has a brand new superstar. His name is Jordan Spieth. What a week, what a performance and golf has a marker for the whole year. How great for golf to have another superstar."

That bogey at the last means Spieth matches Tiger Woods's 18-under total in 1997 and just misses Tiger's 19-under total at the Open in 2000. Hugs with the assembled family and assorted back-slappers and glad-handers, he'll be taking some strong drink this evening, or at least I hope he will.
