US Open: Laura Massaro digs deep to beat Nicol David

Massaro won the US Open in 2011 but lost the 2013 final to David

England's Laura Massaro beat defending champion Nicol David in five epic games to reach the US Open semi-finals.

Massaro rallied from two games down to overcome Malaysia's eight-time world champion 8-11 4-11 11-6 11-8 12-10 in a 71-minute match in Philadelphia.

The 31-year-old will take on Egypt's Omneya Abdel Kawy in the semi-finals.

Men's second seed Nick Matthew, 35, made just five errors as he beat Egypt's Fares Dessouki 11-6 11-2 11-7 to make the last four.

"I think that was maybe my best tactical performance of the week," said Matthew, the 2007 champion.

"I've made the final here a few times in the last few years but never got past that final hurdle so hopefully this is the year that I can change that."

Matthew will face Omar Mosaad for a place in the final after the Egyptian beat England's Daryl Selby 3-2.
