Ahead of the 79th edition of the Masters, Sportsmail counts down the 20 greatest shots ever seen at Augusta National Golf Club. Here are Nos 20-11. Mark O'Meara celebrates his winning putt in 1998 . 20 Mark O'Meara, 1998 . Aged 41, Mark O'Meara's chances of a major championship appeared to have gone despite a fine career and many victories on the PGA Tour. But O'Meara shot two birdies in three holes from the 15th on Sunday and a good approach into the 18th left him with a 20-footer to beat David Duval and Fred Couples. In the manner of his great friend Tiger Woods, he drained it. And he was soon handed his green jacket by Woods in the Butler Cabin. CLICK HERE TO WATCH THE VIDEO . 19 Billy Joe Patton, 1954 . Billy Joe Patton came within a stroke of perhaps the biggest Masters shock of all but narrowly missed out on a play-off with Sam Snead and Ben Hogan. But for a short while it had appeared that an amateur golfer could topple two of the greatest ever to play the game, thanks to his hole-in-one on the par-three sixth on Sunday. Sadly, Patton's hopes were ultimately shot down by a double bogey on the 13th attempting to fly Rae's Creek and reach the green in two. Otherwise his ace would have featured near the very top of this list. Billy Joe Patton hits on the 13th hole... the scene of the double-bogey which ultimately cost him victory .

Seve's second Masters victory featured what he called 'the best golf of my life' over the first four holes, and one 205-yard 2-iron on the fourth was utterly spectacular. But nothing quite sums up the genius of the late, great Spaniard than the way he clinched his four-shot victory over Tom Kite and Ben Crenshaw. An up and down for a bogey would have comfortably sewn up his victory, but showman Seve was having none of it and chipped in for a par four. 17 Byron Nelson, 1937 . Byron Nelson found himself a somewhat daunting six shots behind Ralph Guldahl in the final round of the 1937 tournament. But his comeback was complete on the par-five 13th after he found the cup with a chip for eagle from off the green, while his rival could only manage bogey. Lord Byron came from four strokes down to two ahead in just 25 minutes, and went on to win the first of his five majors by that same margin.

The big Fijian won the green jacket in 2000 but may not have hit a finer shot than this one during the annual par-three tournament on the Wednesday before the 2009 edition. Vijay skimmed his ball across a lake and watched as it rolled onto the green and into the cup for an ace. You'll need to see it to believe it. 15 Nick Faldo, 1989 . With dark descending, in dank drizzle and with wind whipping the course, Nick Faldo became only the second Briton ever to win the Masters after a play-off with Scott Hoch. His nerveless approach over the water on the 11th hole was good, but the putt was even better. Faldo recalled how his caddie, Andy Prodger, told him it was too dark to see the line of the shot, but he stroked it pure and right into the heart of the cup. CLICK HERE TO WATCH THE SHOT .

Charl Schwartzel's victory three years ago is most famous for his rip-roaring finish - four birdies in the final four holes sealed his first major title - but his start was no less incredible. After missing the first green, the South African somehow chipped in from 100 feet for a remarkable birdie. And then, on the third, he slam-dunked his approach from the fairway for an eagle two. Two incredible shots, but the gods truly were smiling on Schwartzel that day. CLICK HERE TO WATCH THE VIDEO .

Phil Mickelson had long carried the burden of being known as 'the best player never to have won a major' - just ask Lee Westwood how wearisome that feels. Lefty had a string of near-misses behind him - six second and third places - when he went toe-to-toe with Ernie Els over the back nine at Augusta that Sunday. And it all came down to the final green as Phil the Thrill sank an 18-footer for birdie under huge pressure to cast off that unwanted reputation once and for all. 12 Fuzzy Zoeller, 1979 . Imagine playing in your very first Masters... and standing over a putt to win, in a sudden-death play-off. It was the first time the Masters had been decided in such a way, was played in the gathering gloom and also included Ed Sneed and the great Tom Watson. In near darkness, Zoeller held his nerve to sink his birdie putt on the 11th hole and make history. 11 Louis Oosthuizen, 2012 . Some might argue that this is the best shot in Masters history - but some would also say it wasn't even the best shot of the day (see the countdown from 10-1). Whatever, it's hard to think of a more perfectly envisioned, controlled and executed long iron in the history of the game. Oosthuizen catapulted himself into the lead (and an eventual play-off) with this 253-yard approach into the par-five second hole that pitched on a sixpence at the front of the green. From then on, it was never going anywhere other than the centre of the cup. Louis Oosthuizen raises his arms and soaks it all in after holing out for an albatross at Augusta in 2012 .
