The world No 24 Malaysians fought hard to upset Indonesia’s world No 8 pair Moh Reza Pahlevi-Sabar Karyaman Gutama 22-20, 21-18 in 79 minutes.

The match was repeatedly delayed as rainwater leaked through the roof of the Macau East Asian Games Dome, forcing officials to mop the court after almost every point.

Wan Arif-Roy King will take home US$29,230 (RM125,128) as champions, while the runners-up earn US$14,060 (RM60,188) from the BWF World Tour Super 300 event.

This is Wan Arif-Roy King’s first win in their three encounters with the Indonesian pair.

The win also ends Malaysia’s 12-year drought in the men’s doubles at the Macau Open. The last Malaysian pair to lift the crown was Hoon Thien How-Tan Wee Kiong in 2013.

Wan Arif-Roy King had previously reached the final of a World Tour event once – last year’s Spain Masters – but had to settle for runners-up.

Their best run this year was making the semi-finals of the Orleans Masters in France, while they also reached the quarter-finals of the Indonesia Masters, German Open and Thailand Open.
