"30 years old, and I've finally won my first world championship!" said Rachael to the packed and exuberant crowd at the presentations.

"It's been an awesome couple of months - I've been world number one and now I'm world champion," said the third seed, who has now increased her WISPA Tour haul to 27 titles.

"I was having a bit of a spiral downwards and over the summer put in a lot more training - and things started to go well," explained the senior Grinham, who has only lost one match in 21 since August when she won the Alexandria Sporting Club Open title in her adopted home country Egypt.

"Winning the British Open last month obviously gave me some confidence - and this will too."

When asked what her feelings were when she was behind in the second game, Rachael replied: "I wasn't thinking I was going to lose the game, or the match - just that I wanted to make her work!

"We know each others games so well, that when we play each other we're often quite hesitant when we make shots - trying to counter the response we're expecting.

"She made a lot of mistakes tonight that she wouldn't normally do.

"I wanted to win quite badly - the fact I was playing my sister didn't really matter!

"This was a championship I really wanted to win. And I am thrilled to have done it at last!"

Asked if she felt any sympathy for her sister, Rachael was quick to respond: "No! After all, she's got three Commonwealth Games gold medals!"

Natalie Grinham conceded that she was "not too disappointed to have lost" - then revealed that she had considered pulling out of the event at the beginning of the week after sustaining a wrist injury on the eve of the tournament.

"It eased off as the tournament developed - but I am disappointed that I couldn't play better tonight. I felt I played much better last night," said the 29-year-old, now based in the Netherlands.

"She played her game and didn't let me play mine. She's very fast - and when she gets the ball she does something with it," added Natalie. "But if I've got to lose to somebody, I'd rather it be her.

"I made a few errors - against her your shots need to be perfect, and mine weren't!

"But I'm really happy to see Rachael playing well again - she's the only player on the current Tour who can trick me."

When asked how she felt about playing in the first ever world final between two sisters, Natalie replied: "It's fantastic. Both of us being in the final, rather than one of us winning it, is almost perfect. Perfect would have been if I'd won it!"
