Spain’s Adrian Otaegui finished second on 12 under, with Englishman Richard McEvoy another stroke back after dropping his only shot of the day at the 18th.

England’s James Morrison was fourth and Lombard finished fifth.

“I am very happy right now. It was a very exciting finish and I still cannot believe it, but my playing partners were really good today and the scores were very close,” said Wu, who slipped into second place when McEvoy birdied the 13th.

A matching birdie at the 13th moved Wu back into a share of the lead before another gain two holes later saw him stand alone at the top of the leaderboard.

Otaegui fired a birdie at the 16th to join Wu at the top of the pile but the Spaniard dropped a shot at the next and pars at the final three holes were enough for Wu to secure the trophy.

“At the 10th and 11th holes I just played two bad shots. I still kept working after that to do my best to make birdies and I did that,” said the Chinese.

“I just kept focused over the last putt and I talked to my caddie and he said, ‘It’s no problem, it’s an easy line so just putt it in the hole.’”
