Madeline Perry into quarter-finals at World Championships

Madeline Perry battled back from two games down to beat England's Sarah-Jane Perry and book a place in the quarter-finals of the World Championship.

The seventh seeded Northern Irishwoman, who at 37 is the oldest player in the tournament, earned a 7-11 10-12 11-9 11-9 11-6 victory in Malaysia.

Perry's win sets up a last-eight meeting with Egyptian third seed Raneem El Weleily on Friday.

The Ulsterwoman beat El Weleily in New York in January.

That victory ended a losing sequence against the Egyptian which included last year's British Open quarter-final.

"A tough 3-2 win and a comeback from me today against a very skilful opponent," said Perry on Twitter after her victory on Thursday.

"Delighted to be into the quarter-finals of the World Championships."

El Weleily continued her run in Penang with a 11-7 11-7 11-1 win over 10th seed Dipika Pallikal of India.
