TOKYO — Denmark's Caroline Wozniacki battled back after a mid-match slump to beat Angelique Kerber of Germany on Friday and book a place in the semi-finals of the Pan Pacific Open.
Needing some strong results on the Asian swing to force her way into next month's WTA Finals, Wozniacki reached the last four with a 6-2 2-6 6-3 win over Kerber, who had won three of their last four clashes.
"It was a tough match -- it always is when I play Angelique," said Wozniacki, who won the Tokyo event in 2010 and was runner-up last year.
