Saturday's WTA Tour round-up

Williams made a number of unforced errors

Venus Williams made a huge number of mistakes but had enough in her game to beat unseeded Czech Denisa Chladkova 6-3 7-6 in their semi-final.

The top seed lost her first service game but still managed to take a 4-1 lead but again dropped her serve before breaking Chladkova to take the first set.

Chladkova stretched Williams in the second set to take a 3-1 advantage before Williams recovered again to lead 5-4.

But Chladkova broke again to level the match at 5-5, and saved a match point in the tiebreaker before finally yielding to the American 7-5.

"I made many mistakes today," said Williams.

"I was just thinking too much about my shot instead of playing it. But I should know how to do it tomorrow."

It was not the best tennis I've played in my life so I'm happy to get through Amelie Mauresmo

She will face second-seeded Amelie Mauresmo of France, who beat Jelena Dokic 7-5 6-2.

Dokic broke to lead 1-0 and against to go 5-4 up after Mauresmo had pulled level at 3-3.

But the fourth seed then dropped her serve to love and netted a backhand volley when holding a break point at 5-5.

Mauresmo broke for the set and Dokic squandered two more chances to break in the second before the Frenchwoman won the last two games to love to wrap up the match.

"There were tough conditions and not the best tennis I've played in my life, so I'm happy to get through," said Mauresmo.

"I think I handled the conditions a little bit better than her, and it got to her mind I think. When she had the break points I just kept fighting and hung in there."

Conchita Martinez Granados recovered from a disastrous start to reach the final with a three-set victory over fellow Spaniard Maria Sanchez Lorenzo.

Martinez Granados dropped the first set 0-6 but bounced back to win 0-6 6-1 6-4.

She will face third-seeded Russian Vera Zvonareva, who beat American Samantha Reeves 6-3 6-4 in the other semi-final.
