Ivanovic and Alisa Kleybanova will contest the year's last singles final on the WTA Tour after the Russian accounted for Daniela Hantuchova of Slovakia 6-3, 6-1.
The 40-year-old Date Krumm had double set point at 5-3, but former No. 1 Ivanovic won six straight games to lead 7-5, 2-0. The Serb served for the match at 7-5, 5-3 but Date Krumm then took charge, saving a match point in the 11th game of the second set and rallying from 4-2 down in the tiebreaker.
Ivanovic was too strong in the deciding set, however, and will play for her second title of the year, and a chance to return to the top 20.
Kleybanova dominated Hantuchova from 3-1 down to shoot for her third title this year on Sunday.
Ivanovic and Kleybanova will meet for the fifth time this year. They are 3-3 in head to heads.
