Top seed Nicol respectively, secured the title in the CIMB Malaysian Open after scoring four-game victories over English opponents in finals of the established international squash event at The Curve Shopping Mall at Mutiara Damansara in Kuala Lumpur.
It was the fifth title triumph in a row for Nicol David in the climax of the $53,500 WISPA World Tour Gold event in front of an adoring local crowd in her country's capital. But her surprise opponent Alison Waters, the fourth seed from London who gate-crashed the final after beating second-seeded Australian Rachael Grinham in straight games in the semis, extended the three-year-long world number one further than before in their tenth career meeting.
David, 25, from Penang, recovered after dropping the third game - her first of the tournament - to win 11-6, 11-8, 9-11, 11-7 in exactly one hour.
"I knew that Alison had made it to the final playing well, and as I had played her in Seoul I knew that it would be hard," said the new champion after clinching her fourth WISPA Tour title this year, and the 38th of her career.
When asked about her fifth Malaysian Open crown in a row, David responded: "It is always a challenge, but I am really helped by the crowd cheering me on."
Though disappointed by her defeat, 25-year-old world No6 Waters was pleased with her performance: "I was delighted to have reached the final and I played well yesterday to beat Rachael - which gave me confidence going into today's final with Nicol.
"This was my first gold final and I was really looking forward to it. It was a question of sticking in there and I had my chances in all the games. I just got my slot selection wrong at the end of a couple of them. But I was generally pleased with my performance and that I got closer to her.
"I think we played a good match and felt this was the closest that I have got to Nicol - so overall it was a good tournament and looking forward to Singapore next week."
