Either Belinda Bencic or Agnieszka Radwanska will earn a place in the top 10 of the WTA rankings on Monday after they both reached the final of the Toray Pan Pacific Open final in Tokyo.
Bencic extended her record over Caroline Wozniacki to four victories in five after breaking serve four times on the way to a 6-2 6-4 success over the Dane.
Seventh seed Radwanska made slightly lighter work of Dominika Cibulkova, securing a 6-4 6-1 success with six breaks of serves.
The duo are also vying for a place at the eight-player WTA Finals at the end of the season, and victory for Bencic on Sunday would be enough to elevate her to seventh spot in the WTA Race with a Radwanska triumph moving the Pole to ninth position.
