British trio win through to boys' last four

Caroline Wozniacki will offer Serena Williams a stern test in their semi-final (PA)

While Andy Murray was making his run to the semi-finals three of his fellow Britons were emulating his performance in the boys' event here at the US Open yesterday. George Morgan, Kyle Edmund and Oliver Golding all won their quarter-final matches, having each won through two rounds on Thursday.

Golding and Morgan, who now meet,came from behind to win their quarter-finals. Golding beat Slovakia's Filip Horansky 5-7, 6-4, 6-1, while Morgan overcame the Czech Republic's Adam Pavlasek 6-7, 6-4, 6-4. Kyle Edmund beat Egypt's Karim Hossam 6-2, 6-4 and now plays the Czech Republic's Jiri Vesely, who is the top seed.

However, Colin Fleming and Ross Hutchins could not follow their fellow countrymen into the semi-finals. The Britons lost their doubles quarter-final against Rohan Bopanna and Aisam-Ul-Haq Qureshi, having failed to serve out for the match the previous evening, when rain curtailed play with their opponents serving at 7-5, 2-6, 6-5 and 15-30. Bopanna and Qureshi won three points in a row on the resumption to take the match.

The semi-finals of the women's singles will be played tonight – the final is tomorrow at 9pm BST – with most eyes focused on the meeting between the overwhelming favourite and the world No 1. Serena Williams, who has not lost on the court since Wimbledon, is still fancied to win her fourth title here, but the American faces her toughest test yet against Caroline Wozniacki. Australia's Sam Stosur and Germany's Angelique Kerber meet in the other semi-final.

While Wozniacki is regularly criticised for topping the rankings without ever having won a Grand Slam title, the 21-year-old Dane has a good record here.

This is her third successive appearance in the semi-finals and she made the final two years ago before losing to Kim Clijsters. "She never gives up," Williams said of Wozniacki. "That's probably the biggest weapon I think you can have in all of tennis."
