The weather has been an issue through the week in Kuala Lumpur. Rains Saturday led organizers to postpone the semifinal between second-seeded Jelena Jankovic and No. 5-seeded Petra Martic to Sunday, ahead of the tournament finals.
Jankovic was to have played twice Saturday but her quarterfinal opponent, sixth-seeded Ayumi Morita, withdrew with a shoulder injury.
Eleni Daniilidou finished off a quarterfinal match with a 6-2, 3-6, 6-2 decision over Olivia Rogowska. Daniilidou had been ahead 6-2, 3-2 when rain forced a suspension Friday.
Hsieh took a spot in the semifinals when top-seeded Agnieszka Radwanska withdrew with an elbow injury. She topped Daniilidou 6-0, 4-6, 6-1 Saturday in collecting her first WTA finals slot. She has won 18 ITF events, however.
Hsieh didn't allow Daniilidou a break-point opportunity in the first or third sets when she won more than 70 percent of the points on serve. The match took nearly 5 hours to complete due to a pair of rain delays.
Jankovic will be looking for her first spot in a final since last August. Her most recent WTA title -- the 12th of her career -- was two years ago. Martic, like Hsieh, has never played in a WTA championship match.
