Victoria Azarenka of Belarus ended Julia Goerges' 10-match winning streak 6-4, 6-2 to reach the Madrid Open final against Petra Kvitova of the Czech Republic on Saturday.
Kvitova ousted sixth-seeded Li Na 6-3, 6-1, breaking the Chinese player six times.
Azarenka and Kvitova will each be chasing her third WTA title of the year Sunday on the Caja Magica clay court.
Late Saturday, the men's semifinals feature a Rafael Nadal-Roger Federer clash in Madrid for a third straight year, then Novak Djokovic takes a 32-match winning streak into his meeting with Thomaz Bellucci of Brazil.
By making the final, Azarenka ensured she would move up one spot to a career-best No. 4 in the new world rankings Monday. The ranking will also be the best ever for a Belarusian, eclipsing Natasha Zvereva, who reached No. 5 in 1989.
Azarenka's win also made up for losing to Goerges in Stuttgart two weeks ago, when she had to withdraw with a shoulder injury after winning the first set in the first round. Goerges went on to win her second WTA title in Stuttgart. This week, the German toppled top-ranked Caroline Wozniacki, but couldn't break Azarenka.
Kvitova won titles this year in Brisbane and Paris, where she beat Kim Clijsters in the final and made her top 15 debut.
