Radwanska in Shenzhen semis

Beijing - Number one seed Agnieszka Radwanska strolled into the semi-finals of the WTA Shenzhen Open in straight sets on Wednesday, the only seed left in the $500 000 tournament.

Radwanska, the world number five and winner of the WTA Finals in Singapore in November, disposed of her second home opponent in as many days, defeating Wang Qiang 6-3, 6-2 in little over an hour.

But Canada's Eugenie Bouchard, the number six seed, went out at the hands of Timea Babos of Hungary, 6-4, 6-4.

The tournament in the southern Chinese boom town neighbouring Hong Kong has been littered with surprises and early exits, some of them to illness or injury.

But Radwanska will now be an even hotter favourite, as world number 70 Babos - whom she will meet in Saturday's final if they both win their semis - is her highest-ranked remaining rival.
