Defending champion Laura Massaro was eliminated from the Professional Squash Association World Series Finals as the group stage of the tournament concluded.

The English player began the day at the top of Group B in the women's event and knew a victory over France's Camille Serme would secure her spot in the semi-finals.

Serme would prove dominant throughout the encounter to book her place in the last four for the second consecutive year.

She emerged as a 11-7, 11-5 winner, leaving Massaro fearing for her semi-final spot.

Massaro knew she could be eliminated on percentage of games won should Egypt's Raneem El Welily overcome England's Sarah-Jane Perry.

The world champion would achieve the feat by beating Perry 11-6, 11-9, which ensured she topped the group.

Serme progressed in second place, with Massaro and Perry suffering elimination.

The semi-final line-up was confirmed when Egypt's Nour El Tayeb overcame New Zealand's Joelle King in a dramatic Group A match.

The match went to a deciding game, with both players having match balls at one stage, but El Tayeb would seal victory by a 7-11, 11-7, 13-11 score.

She progressed with Nour El Sherbini, with the Egyptian having already sealed her spot in the last four after two wins.

El Tayeb will face El Welily in an all-Egyptian semi-final, with Serme meeting El Sherbini.

Men's second seed Ali Farag booked his place in the semi-finals, following a decisive victory in Group B against compatriot Karim Abdel Gawad.

Both players had a chance to progress, but Farag dominated proceedings to triumph 11-5, 11-5.

He finished second in the group, with Germany’s Simon Rosner having sealed a third straight win by beating France's Grégory Gaultier 11-8, 12-10.

England's Nick Matthew continued his swansong before retirement by beating Egypt's Mohamed Elshorbagy 11-6, 11-6 in Group A to top the standings.

Both had already secured semi-final places.

Colombia’s Miguel Ángel Rodríguez and Egypt’s Tarek Momen hoped to end their participation on a high when they played each other.

The latter would emerge as an 11-5, 8-11, 11-8 winner.

Matthew will face Farag in the semi-finals, with Elshorbagy set to meet Rosner.
