World Squash: Laura Massaro reaches last eight in Penang

Jenny Duncalfe and Laura Massaro

Laura Massaro will carry English hopes into the last eight of the squash World Championship after beating compatriot Jenny Duncalf 3-0 in Penang, Malaysia.

Massaro, the world number two, won 11-9 11-6 11-4 and will take on Malaysia's Low Wee Wern for a semi-final place.

Malaysian top seed and seven-time champion Nicol David beat Egyptian qualifier Heba El Torky 11-6 11-3 11-4.

English fourth seed Alison Waters suffered a shock 11-3 11-9 7-11 11-3 defeat to Egypt's Nour El Sherbini.

"Not the best after my birthday," Waters, who turned 30 on Wednesday, told the Women's Squash Association website.

"But Sherbini played really well. She was confident and was controlling the 'T'. The headstart she had was just too much for me."

Ireland's seventh seed Madeline Perry battled back from two games down to beat Sarah-Jane Perry of England 7-11 10-12 11-9 11-9 11-6.

The tournament is in fact the 2013 World Championship, finally taking place now after organisers failed to secure a venue during the calendar year.

Malaysian superstar David is the big draw, her status evident in the fact that the event is being held at the Nicol David International Squash Centre.

The 30-year-old has not lost a World Championship match since 2007, and beat Massaro in the 2012 final in the Cayman Islands.
