Phil Mickelson received the green jacket from Ãngel Cabrera, the 2009 Masters champion, after winning the 2010 Masters Tournament at Augusta National on Sunday. More Photos »  Riding a wave of emotion that began when Amy, who has been treated for breast cancer for the past year, was strong enough to come to the Masters this week, Mickelson shot a flawless final-round 67 for a 16-under-par total of 272 and became the fifth golfer to win his third green jacket. Just for fun, and maybe for the memory, he rolled in one more birdie putt at the last hole for a three-stroke victory over Lee Westwood of England, who closed with a 71. He was four strokes ahead of Anthony Kim, who charged home with a 65, tied for the low round of the tournament.  After walking calmly on the edge of calamity, saving par from the woods, making birdies off the pine straw, the bunkers and the fairway, the 39-year-old Mickelson embraced his caddie, his wife and his children, waved to his fans, and nearly broke down when he thought about what it all meant.  At the jacket presentation ceremony next to the 18th green, Mickelson choked back tears.  “We’ve been through a lot this year,” he said, his voice breaking. “And it means a lot to share some joy together. She’s an incredible wife, an incredible mother, and she’s been an inspiration to me, going through what she’s been through.  “This has been an incredible week, and it’s something we’ll share and remember the rest of our lives. It’s one of the best things we’ve gone through. To feel this kind of jubilation is something we’ll never forget.”  Unforgettable would be a fitting description for the day, and for how Mickelson went about his business Sunday on a hard, fast golf course. He did not bogey a hole. He did not lose his head in the maelstrom of noise that was erupting all over Amen Corner. He stared down Westwood, was never concerned about the birdie barrage from Kim and put together a how-to manual for playing a final round at Augusta.  “I shot 71 at the end of the day, which is not a terrible score around Augusta when you’re in the lead,” Westwood said. “Phil shot 67, which generally wins major championships when people are there or thereabouts going into the last round. He hit good shots when he needed to around the back nine. He could quite easily have eagled 13.  “So, yeah, I think Phil won that one fair and square.”  Perhaps one day, the historically minded Augusta National members will place a plaque somewhere near the trees in the pine straw to the right of the 13th hole, where Mickelson hit the type of shot that defines his style — a no-margin-for-error laser-guided 6-iron from 207 yards, through a 4-foot window in the pines, over the tributary of Rae’s Creek to a soft landing, 4 feet from the hole for eagle.  Not that he made the putt, once again showing that no shot is too hard, or too easy, for Phil Mickelson. But the birdie did give him a little breathing room while the 24-year-old Kim was on one of his birdie-birdie-eagle-birdie tears beginning at the 13th hole.  Kim set the record for birdies in a round last year at Augusta, when he had 11. As inconceivable as that might seem, so was the six-birdie, one-eagle binge he went on Sunday. Coming when he was in a position to actually hang up a score that might scare someone, it was a masterpiece for any golfer, let alone a wounded one.  Kim said he had a torn ligament in his left thumb, an injury that has been bothering him since last season and for which he is pondering an operation as early as next week. After winning the Shell Houston Open last week and finishing third in the Masters, he may want to reconsider.  After making three birdies and one bogey on the front nine, Kim cut loose on the second nine with some pin-seeking. He reached eight under with a chip-and-putt birdie from the edge at the 13th, got to nine under with a 9-iron to 6 feet at the 14th and then hit a 5-iron into the par-five 15th hole to 15 feet and made that for eagle to reach 11 under. He got to 12 under with a 20-footer at the 16th, which was just about the time Mickelson was pondering his predicament at the edge of the woods at the 13th hole.  Mickelson saw his opening and he took it, just as he did at the ninth hole, when, faced with a small opening in the woods to the right, he whacked an iron out to the base of the hill on the right side of the green. After a pitch, he made a slippery putt. And on the 10th, when he drove the ball into a small group of magnolias to the right of the fairway, he somehow threaded a low punch to the base of the green where he, naturally, pitched on and tapped in.  What he saw at the 13th was enough of a gap to convince him he could pull off the shot and move closer to the finish line. If he pitched out into the fairway to lay up, he would face a wedge from a tight downhill lie into the sliver of green.  “I was going to have to go through that gap if I laid up or went for the green,” he said. “I was going to have to hit a decent shot. The gap was a little bit wider — it wasn’t huge, but it was big enough, you know, for a ball to fit through.  “I just felt like at that time, I needed to trust my swing and hit a shot, and it came off perfect.”  Like the entire day. This was an old-time Masters scene, one that probably could have been dreamed up by Frank Capra, but probably not made into a film. The ending was just too implausible.

Phil Mickelsonâs hammer-down, all-or-nothing approach may have cost him a major championship or two in the past, but it won him his third green jacket on Sunday.
