The South Korean was one of a record-breaking nine players to start the third round with a share of the lead at Doha Golf Club, but he pulled clear from the pack with seven birdies to move to 15 under par for the tournament.
Wang was crowned the Sir Henry Cotton Rookie of the Year in 2016 after claiming back-to-back European Tour wins last spring in Morocco and Mauritius and finishing runner up in the Nedbank Golf Challenge hosted by Gary Player in November.
He has hit the ground running in 2017, finishing 11th in last week’s Abu Dhabi HSBC Championship, and the windy conditions in Doha have proved to his liking, as he produced a faultless display of shot-making to spread the field.
South African Jaco Van Zyl and Spaniard Nacho Elvira will lead the pack chasing Wang in the final round after both players signed for rounds of 68. Elvira was threatening to keep pace with Wang until a double bogey six on the 15th hole blotted his scorecard, but the Challenge Tour Graduate of the Year hit back with birdies on the 17th and 18th holes to join Van Zyl on 12 under par.
Van Zyl’s compatriot Thomas Aiken is a further shot back on 11 under par after a round of 69, while Ryder Cup pair Rafa Cabrera Bello (66) and Andy Sullivan (70) are in a group of five players tied for fifth position on ten under par.
“I don't want to think about the win,” said Wang. “I just want to focus on my own game. My irons and putting are really good this week. So I think I have a good chance to win.”
“I only missed a few greens today. That's the key to my seven under. My putting was really good, too. I think everything is good right now. I like this course. I like the wind. I like the green conditions. It's pretty nice for me.”
“I think (finishing second at) Nedbank was bigger than the two wins for me. Nedbank is really big tournament, and there's a lot of great players. I learned a lot from it.”
Scott Hend was the only Australian to make the cut but after another round of 72 is in a share of 48th position at 3 under and some 12 shots from Wang’s lead.
New Zealander Ryan Fox made a good move with his third round of 67 to share 29th place at 5 under.
