Wang wasted little time in the sudden-death playoff, claiming a birdie on the 18th first hole as Lagergren and Van Zyl could only par.
The 24-year-old from Bath, who played in the 2013 Walker Cup team and who last year topped the rankings of the Challenge Tour, the main circuit's feeder league, posted his second top 10 in three events to earn his berth.
Wang entered the final round, holding a three-stroke lead, and the advantage evaporated on the back nine on Sunday at the par-72 layout. I just lingered along until I made a nice one on 13. "I'm so happy", the 2016 rookie of the year said after a closing 71.
"This feels really fantastic for me", he said. It's a really long day for me.
South African Thomas Aiken briefly replaced Lorenzo-Vera in the leading group with a fifth birdie of the day on the 16th but when he dropped a shot on the next, Wang sank his third birdie of the day on the 16th to hit the front again, before another poor chip-shot on the 17th set up the dramatic finale.
"I was really nervous on the back nine". "I shot seven under and I'm so happy that I didn't make any bogeys today". I've really got a lot of confidence right now, I just want to play another tournament.
"I've always imagined that I will play there and maybe now I have a chance to play the Masters. I missed a lot of greens but my chipping was really good today so I saved everything and finally I won".
Sitting at the heart of the European Tour's Middle East swing, the tournament attracted over 25,000 spectators in 2016 and was broadcast to a global TV audience of over 400 million, organisers said a day before the event kicked off on Thursday. I think I was under control all the way through the last couple holes, and then my mind wasn't in the right place on a couple drives in the end. "I'm excited to play tomorrow", he said.
