The 10th-seeded Henin-Hardenne is favored to win the title, but the Roland Garros crowd will be pulling for its home country player - the number 21 Pierce.
Since returning to the court in April after injuries and a serious viral infection, the 23-year-old Henin-Hardenne has won 23 straight matches. The Belgian has three career Grand Slam titles, including the French Open in 2003, and has beaten Pierce all three times they have met.
Pierce was born in Montreal to a French mother and American father and won her French Open title in 2000. Though she trains and lives in the United States, Pierce plays for France. At 30, Pierce will be the oldest women's Grand Slam finalist since 37-year-old American Martina Navratilova was the runner-up at Wimbledon in 1994.
