Graf Gaffs but Rallies to Reach Leipzig Semis

LEIPZIG -- Steffi Graf, playing one of her worst first sets in memory Thursday, woke up in time to beat Austria's Judith Wiesner 1-6, 6-3, 6-2 at the Leipzig Open.

But Graf's play was riddled with errors as she sleepwalked through the first set. The world No. 1 had to fight a set point to avoid a whitewash by Wiesner, ranked 20 places lower.

Graf takes on compatriot Anke Huber, the no. 4 seed, in Saturday's semifinal. Huber, the defending champion, edged no. 6 Magdalena Maleeva of Bulgaria 6-4, 7-6 (8-6) in a rematch of last year's final.

Second seed Arantxa Sanchez Vicario was unexpectedly beaten 6-3 7-6 by unseeded Helena Sukova on Friday.

The 31-year-old Czech upset Sanchez Vicario 6-3, 7-6 (7-5) to advance to the semifinals. She will play Iva Majoli of Croatia, who struggled to best American Olympic champion Lindsay Davenport 6-7 (8-10), 7-6 (7-2), 7-6 (7-3) in Friday's other quarterfinal action.

Lyon Grand Prix. Tim Henman of Britain and Yevgeny Kafelnikov of Russia gained the semifinals of the Grand Prix tennis tournament Friday with quarterfinal wins.

Henman, the surprise quarterfinalist at Wimbledon this year, beat Slovak Karol Kucera 7-6 (8-6), 6-2.

Second seed Kafelnikov bested Magnus Gustafsson of Sweden 5-7, 7-5, 6-3.

Singapore Open. World number two Michael Chang routed Javier Frana of Argentina 6-4 6-1 to reach the semifinals of the men's Singapore Open on Friday.

Sweden's Thomas Johansson reached the semifinals at the expense of second seed Richard Krajicek after the Dutchman failed to start the third set and retired with a knee injury.
