TOKYO (Reuters) - Rising Swiss star Belinda Bencic beat Denmark's Caroline Wozniacki on Saturday to storm into the final of the Pan Pacific Open.

She will face Poland's Agnieszka Radwanska.

Bencic defeated Wozniacki 6-2, 6-4, her fourth win in a row over the former world No. 1, to reach her fourth WTA final since June.

If the 18-year-old wins, she will break into the world's top 10 rankings for the first time.

Wozniacki was the top seed for the event but had no answer for Bencic.

The latter won her first WTA title at Eastbourne in June, then followed up by winning the Canadian Open in August.

Radwanska, chasing her first WTA title in more than a year, carved out a 6-4, 6-1 win over Slovakia's Dominika Cibulkova.
