Asal recovered from dropping the opening game to beat his Egyptian counterpart 12-14, 11-4, 11-7, 11-3 in a gripping final at the Mall of Arabia.

World number two Nouran Gohar clinched the women's title with an 11-9, 11-6, 8-11, 11-8 victory over Hania El Hammamy in another all-Egyptian affair.

Asal, the world number 12 who had beaten reigning world champion Tarek Momen on his way to the final, dropped the opening game before rallying to claim the biggest win of his career.

The world junior champion was superb after losing the first game and proved too strong for Elshorbagy, who was making a record fourth appearance in the showpiece match at the World Tour Finals. 

Gohar made a bright start to the women's final and took a two-game lead - a deficit El Hammamy overcame to beat Nour El Tayeb in the last final at this event.

El Hammamy briefly threatened to repeat those heroics but Gohar, the third seed, held her nerve to close out victory.

The triumph handed Gohar her first PSA World Tour finals crown and first title of the season.

"If you want to beat Hania then you have to play over your best and be consistent," said Gohar.

"She is the hungriest player right now on tour. 

"I know how it feels to be her age and beating the top players, so I knew she would be confident on court and I couldn’t take it for granted being 2-0 up. 

"She pulled it back and she was trying to win the match, I’m just pleased with the way I performed."
