World number one Justine Henin stayed on course for a rare French Open hat-trick when she outplayed Serbia's Jelena Jankovic 6-2 6-2 on Thursday to reach the final.
Top seed Henin, trying to become the first woman to win three successive crowns at Roland Garros since Monica Seles in 1992, will face another player from Serbia in Ana Ivanovic in Saturday's title match.
Fourth-seeded Jankovic, 22, lacked composure when it mattered.
Hampered by a weak serve, she was never really in contention and bowed out by sending a forehand wide on the first match point after 8O minutes of play.
The 25-year-old Henin, who also won here in 2003, will still top the rankings next week after world number two Maria Sharapova lost 6-2 6-1 to Ivanovic in the other semi-final earlier on Thursday.
