Rubin sets up Dementieva rematch

Rubin is seeking revenge over Dementieva after last week's defeat

Chanda Rubin defeated Japan's Akiko Morigami in three sets to reach the final of the Polo Open in Shanghai.

Rubin ended hopes of a Japanese player appearing in the final with a 6-0 5-7 6-3 win.

Rubin, the second seed, will meet Elena Dementieva on Sunday in a repeat of the Bali final a week ago, which the Russian won.

Dementieva defeated third seed Ai Sugiyama, also of Japan, 6-1 3-6 6-3 in the first semi-final.

The top seed looked tired in the second set and several double faults proved crucial as Sugiyama levelled the match to the delight of the crowd.

However, Dementieva steeled herself in the decider and wore down her opponent with some punishing groundstrokes.

"I can't say there was any point where I felt I could win the match. It was a very close match," said Dementieva.

"Only when it was love-40 on her serve did I feel a little chance to win."

Despite her easy victory over Rubin in last week's Bali final, Dementieva is taking nothing for granted.

"It's difficult to play someone you just played and beat very easily," she said.
