Dustin Johnson, the world number one, achieved a record-breaking 20 under par as he won his first Masters at Augusta.

The American managed to hold off Sungjae Im from South Korea and Australian Cameron Smith by securing a four-under 68 score on Sunday.

The Northern Irishman Rory McIlroy’s path to try and secure the top spot came too late as finished back in tied fifth.

The defending Champion Tiger Woods carded a surprising 10 on the par-three 12th but he managed to recover and finish the tournament with one under par.

Bryson DeChambeau, winner of the US Open in September, was the favourite coming into the tournament but his inconsistencies during the week and his final-day 73 secured him with a two-under par for the Augusta Masters.

Justin Thomas, world number three, finished at 12 under which positioned him in fourth place.

The incredible performance of Johnson allowed him to beat the record lowest winning score of 18 under par which was set by Tiger Woods in 1997 and Jordan Spieth in 2015 during the unprecedented staging of the Masters in November.

The American described that he was nervous all day as the course was tough. He is now set to defend his title in five months when he competes in the Masters again in the usual April tournament period.

“The Masters is for me the biggest tournament and the one I wanted to win the most. I am just very proud of the way I handled myself and finished off the tournament.” Said Johnson.

“It still feels like a dream. As a kid, I was dreaming about winning the Masters and having Tiger put the Green Jacket on you still feels like a dream.

“But I am here and what a great feeling it is. I could not feel more excited.”

He has now become the first world number one to win the tournament since Woods did back in 2002. A win owed to the soft November course conditions and brilliant all-round qualities of the American.

Johnson seemed to look comfortable on the course all week and the straight-faced American maintained his high class and form as he won his second major title, four years after he won the US Open.

He provided some calm after quite literally an electric mid-point in the week as electrical storms delayed play with there being briefly being nine players tied at the top on the leaderboard on Saturday.

The foundation of his win was started from his amazing achievement of reaching 16 under par after the first three rounds. He became the first Masters player in history since Spieth to achieve such a great start.

On such an iconic stage, Johnson was not fazed by the high pressure environment and produced one of his best performances to date.

The 36-year-old, who had failed to four major titles after holding a 54-hole lead, maintained full concentration and professionalism as he made a par-save at two and birdied the third before falling back after successive bogeys.

By the sixth hole, he had recovered with a birdie and then again at eight which saw the American lead Smith by two heading into the ninth hole.

His success continued at 13 when he stroked in a birdie and made it three in a row through 14 and 15 to achieve 20 under par.

Johnson received well-deserved applause from the few spectators that were gathered around the course as he tapped in for par at the 18th hole.

European Ryder Cup captain Padraig Harrington stated that Johnson had transformed himself into a dedicated and disciplined player as he took the course very seriously.

“I think most people would have a different image of Dustin Johnson, but he works really hard. He’s improved his weaknesses, he’s got a big team out there, he’s in the gym, he’s got the physios, he’s really dedicated.”

The best player in the world has definitely deserved wearing the iconic Augusta Masters Green Jacket in 2020.
