Ivanovic, Date Krumm reach Bali semifinals

Wild-card Kimiko Date Krumm edged top-seeded Li Na 6-4, 3-6, 6-4 at the Tournament of Champions on Thursday.

The 40-year-old Date Krumm will face Ana Ivanovic, who dispatched third-seeded Anastasia Pavlyuchenkova 6-0, 6-1. The unseeded Ivanovic won the first 11 games against Pavlyuchenkova.

The Serb said winning the Generali Ladies in Austria three weeks ago, ending a two-year title drought, boosted her confidence.

Date Krumm came from 3-1 down in the final set to beat China's Li, converting her fourth match point when Li double-faulted.

Second-seeded Aravane Rezai will play Alisa Kleybanova, and fourth-seeded Yanina Wickmayer will meet Daniela Hantuchova to complete the semifinals lineup in the eight-woman tournament.
