"There's a naive innocence about him which, in this day and age, is quite loveable."
Bubba Watson is the 17th man to win the Masters twice. He is off to Butlers' Cabin to see if the cut of that Green Jacket suits him.

"Golf has a new superstar. If you didn't know who Jordan Spieth was before this week, you will do now."
Paul Azinger
Former United States Ryder Cup captain on BBC TV
"It makes me want to cry. Bubba Watson has put his stamp on the game and taken a second step into the history books. He's such an imaginative, clever player, a raw, natural talent. Almost a genius, but genius looks a lot like hard work to me. He doesn't mess around, he works hard."

"This is a moment that belongs to Bubba Watson. This is the most glamorous of the majors, the one we wait the longest in anticipation for. He crumples with emotion, putting his hands on his knees.
"You can see the tears in his eyes. He has joined Tom Watson as a two-time Masters winner. It has been a tremendous performance and moves him into the top five in the world. The emotion is etched all over his face."
Bubba Watson is within a whisker of a crowd-pleasing birdie. It holds on the brink though and Watson has the strokes in hand to know that all he need to do is press the back of the ball to seal his second Masters title.
He duly does. And here come the waterworks.
Jordan Spieth does his duties, tapping down the earth on a five under campaign.
The crowd loop round to surround Jordan Spieth and champion-elect Bubba Watson in a chorus of cheers as they head up to the green.
Luke Donald:, external Bubba was totally in control of his golf Thursday and Friday, looks to be a deserving winner again. I'm off to Nevada Bob's to buy some left handed clubs - seems like the secret around this place #Lefties.
Graeme McDowell:, external Crazy stat. 6 of the last 12 Masters champs are lefties. Moving it right to left all day.......you can talk to a slice, hooks don't listen!

"This is what every golfer dreams of, climbing up to the 18th green with thousands of people around."
Bubba Watson affords himself a sip of water and a smile as he waits for Jonas Blixt and matt Kuchar to clear off the 18th green. Wife Angela and son Caleb are preparing the welcome committee up ahead.
Kuchar has finished with two bogies to end on two under, the impressive Blixt is done and dusted on five under. Might we see him at Gleneagles later this year?
That is for then, now it is time for the headliners.
Par four, 465 yards
An uphill, dogleg right with two bunkers to be avoided on the left elbow of the fairway and woods on the opposite side. Two bunkers protect a sloping, double-tiered green on one the most famous finishing holes in golf.

"There's a clench of the fist, Bubba Watson knows that was so, so important. The past six Masters champions have all broken 70 in their first rounds. Going into today's round, only one man had managed that in this tournament; Bubba Watson."
Not a waver so far from Bubba Watson. He taps in his par putt. Feet up on the dashboard, cruise control engaged and he is surely on his way to his second Green Jacket.
Jordan Spieth with a floaty chip from off the green at 17. It gets the crowd on their feet, but they stay grounded as the ball runs past.
Jonas Blixt leaves his second shot short of the green on the last. No last-hole heroics to haul the leader back within range over there.
-8 B Watson (US) after 16; -5 Blixt (Swe) 16, Spieth (US) 16; -4 Jimenez (Spa) F; -3 Kuchar (US) 17.
Selected others: -1 Westwood (Eng) F; E McIlroy (NI); +1 Rose (Eng) F, Donaldson (Wal) F, Scott (Aus) F; +2 Poulter (Eng) F; +6 Gallacher (Sco) F; +9 Clarke (NI) F, Lyle (Sco) F.
Jordan Speith and Bubba Watson side by side on the right side of the 17th fairway. A chance to compare and contrast how they cope with this.
Spieth is first up and lands one on the gallery circling the right hand edge of the green. Watson sends his scuttling up the edge of the green, keeping clear of the bunkers guarding the front of the green. His to lose now. And it would have to be a Jean van de Velde-level meltdown.
Jonas Blixt holes out a really gutsy par putt from range on 17 to maintain his record of not yet having three-putted at the tournament and keep a modicum of pressure on the leader behind.
Justin Rose tells BBC Sport how he feels about his two-over par round to end plus one for the tournament: "A lot of frustration. It was a tricky start, The pace of greens on three an four were exceptional and got in your head from that point. I got a but gun shy as a result which showed up on 15 and 16. I swung the club pretty well and putted my line well but struggled with the speed. I just didn't get off to the start I was looking for."
