Martina Hingis set up a US Open semi-final against Venus Williams with what turned out to be a hard-fought win over two-time champion Monica Seles.

Top seed Hingis stormed through the first set in just 14 minutes for the loss of a mere six points - and she looked poised for one of the quickest ever victories in a clash between two top players.

But the second set was a different story as sixth seed Seles, who had struggled to find any consistency early on, started to fire off winners from the back of the court.

But Williams won their most recent encounter, the Wimbledon semi-final, and Hingis is looking for revenge.

"I would like to turn it around," she said. "The last time I was playing very well again and this time I hope it's going to be a different story."

Seles said she knew exactly where things had gone wrong: "I really started the match very sluggishly," she admitted. "I tried to get back into it. But it was way too late.

"I have to look at why that keeps happening. You have days when your timing is off. But against her, I have more days like that than I should.

"Maybe I panicked a little bit and against Martina you aren't going to get any easy points. I made so many unforced errors and the set was gone."
