Wang also finished runner-up at the Nedbank Challenge in South Africa late last year, adding further to the riches he has acquired since joining the European Tour in 2016 in addition to securing the Sir Henry Cotton Rookie of the Year honours in the process.
It was Wang’s third European Tour victory in just 29 appearances, with only Matteo Manassero (19 years and 206 days) and Seve Ballesteros (20 years and 77 days) achieving that haul of titles at a younger age.
Wang, who won the Trophée Hassan II - also after a play-off - and the AfrAsia Bank Mauritius Open last year, also joins 2009 US PGA Champion YE Yang as the most prolific Korean winner on the European Tour.
Wang will also move to around 40th in the world ranking, making him Korea's highest ranked male golfer and he now appears well placed to secure his first start at the Masters in April.
“I really didn't expect that I would win this week,” said Wang. “I just keep trying to make birdies, trying to save par and finally won this week. I've got a lot of confidence from this week, and I learned from the other players about the course. I feel really good right now and just want to win another one.”
“I was really nervous. It's really long day for me. I missed a lot of greens on the back nine. But my chipping was really good, so I saved every par. So I think that's the key that I won this week.”
France’s Mike Lorenzo Vera just missed out on joining the trio in the play-off after a dramatic finish to his final round. Having reached 16 under par with his seventh birdie of the day on the 13th hole, he found the water on the 15th and dropped his first shot of the day before chipping in for eagle on the 16th. However, he then dropped another shot on the 17th before entering the water hazard again on the last hole and making another bogey, to sign for a round of 66 and finish on 15 under par, one shot outside the play-off.
South African Thomas Aiken also missed out by a single stroke following his only bogey of the day on the 17th hole in a round of 68.European Ryder Cup star Rafa Cabrera Bello closed with a round of 68 to share sixth position with fellow Spaniard Nacho Elvira (70) and England’s Jordan Smith (66).
Scott Hend was the only Australian to make the cut but finished well back in 60th position while New Zealander Ryan Fox was unable to capitalise on his opening three days, a final round of 78 seeing him slip to 64th position.
The European Tour now moves to Dubai for the final event of tis Middle Eastern Swing, the Dubai Desert Classic.
