The 20 year old was high on confidence after beating Nacho Elvira in a play-off for the Trophée Hassan II title, and he capitalised on Bangladeshi Siddikur Rahman’s late collapse by birdieing the last to win by one shot at Four Seasons Golf Club Anahita.
Siddikur had a three-shot lead on the 16th tee, but double-bogeyed that hole and dropped another shot at the par three 17th to head up the last level with Wang. Both players hit their second shots into the par five right of the green, and it was Wang who got up and down for a crucial birdie to finish on six under par.
They were the only players to end the €1million event in red figures as strong winds made for tricky conditions on the Mauritian east coast, with Belgian Nicolas Colsaerts and Argentine Estanislao Goya sharing third place on level par.
Australian Andrew Dodt, the leader for the first two rounds, had to settle for fifth place, while young South African Brandon Stone took sixth on two over.
“I can’t believe that I’ve won two weeks in a row," said Wang. "I’m so excited right now and really happy that I have won. I probably had luck on my side today. I wasn’t even thinking about winning this week until the 16th.
"I missed a lot of putts so I thought I didn’t have any chance. I hit my second shot into the 18th well, but it just went off the green. I was just trying to make par, but I hit the bunker shot close and gave myself an easy putt for a birdie. It was fantastic. I hope I can win three in a row, but next week is a really big tournament and it’s my first time in Ireland, so I’m not sure. I’ll be trying my best.”
Terry Pilkadaris and Jason Scrivener tied for 7th which for Scrivener was his second top ten in succession while Scott Hend collapsed over the closing nine dropping seven shots in his last six holes after being very much in the mix making the turn.
The European Tour now moves to Ireland where they play this week's Irish Open at the K Club in County Kildare.
