Bubba Watson started the day by watching the rarest shot in golf. He ended another thrill-a-minute yesterday at Augusta National with a signature shot of his own to win the Masters. So deep in the trees right of the 10th fairway that he couldn\'t even see the green, Watson hooked a wedge off the pine needles from 141m to about 3m from the hole. That set up a par, good enough to beat Louis Oosthuizen on the second playoff hole. \"If I\'ve got a swing, I\'ve got a shot,\" Watson said. It was Oosthuizen who set the tone for this wild day with a double eagle - only the fourth in Masters history - on the par-5 second hole when his 4-iron from 231m landed on the front of the green and rolled some 27m into the hole for a 2. \"Somehow it fell in my hands today,\" said Watson, who closed with a 68. \"It\'s amazing. It\'s a blur, the last nine holes I don\'t remember anything. Somehow I guess I cried all my tears out.\" He was blubbering hard on the 10th green, shoulders heaving, for so many reasons. Just two weeks ago, he and his wife adopted a baby boy, Caleb. The first person on the green was his mother - his father died right after the Ryder Cup in 2010. And suddenly, the powerful lefty with a million shots in the bag was a major champion. \"I never got this far in my dreams,\" Watson said in Butler Cabin, where defending champion Charl Schwartzel helped him into the green jacket. \"It\'s a blessing. To go home to my new son, it\'s going to be fun.\" Oosthuizen was trying to join Gene Sarazen in the 1935 Masters as the only major champions to win with a double eagle in the final round. The former British Open champion made one clutch putt after another on the back nine, none more important than a 1.2m putt on the 18th for a 69 to force the playoff. Both had a good look at birdie at No 18 on the first extra hole and missed. Watson, dressed all in white and using a pink driver, hooked one into the trees and it appeared he would have no shot at reaching the green. Oosthuizen followed him, clanged off a Georgia pine and was left with 211m to the green. His approach came up short. That\'s when Watson, who rarely hits a shot on a straight line, came up with the most magical shot of his life. \"I was there earlier today, during regulation,\" he said. \"So I was used to it. I knew what I was facing there. I had a good lie, had a gap where I had to hook it 40 yards [36.5m] or something. I\'m pretty good at hooking it.\" Oosthuizen was in the fairway. All he could see was a corridor of fans leading into the woods. \"I had no idea where he was,\" Oosthuizen said. \"Where I stood from, when the ball came out, it looked like a curve ball. Unbelievable shot. That shot he hit definitely won him the tournament.\" They finished at 10-under 278, two shots ahead of four players who kept it close and made the Masters as compelling as ever. Phil Mickelson, playing in the final group for the fourth time, recovered from a triple bogey on the par-3 fourth hole and still managed to stay in the game. He could only make two-putt birdies on the two par 5s on the back and shot 72. \"It\'s disappointing that I didn\'t grab that fourth green jacket,\" said Mickelson, whose wife and three kids flew in from San Diego on Sunday. Tiger Woods went from the favourite to not even a factor on the weekend. He closed with a birdie on the 18th for a 74 and had his highest score ever at the Masters as a pro, finishing at 5-over 293 - 15 shots out of the lead. This, from a guy who only two weeks ago won by five shots at Bay Hill. He tied for 40th with US Open champion Rory McIlroy, also favoured to contend. Gerry \"Bubba\" Watson, a 33-year-old from the Florida Panhandle, won for the fourth time in his career and moves to No 4 in the world, making him the highest-ranked American in golf.
