Bali, Indonesia (My Sportsbook) - Top-seeded Frenchwoman Marion Bartoli and sixth-seeded Spaniard Maria Jose Martinez Sanchez secured berths in Saturday's semifinals at the $600,000 Tournament of Champions tennis event.

Bartoli went 2-0 and captured this week's A Group with a 6-3, 6-2 victory over seventh-seeded Israeli Shahar Peer (1-1) in Friday's round-robin action on the indoor hardcourts at the Bali International Convention Centre.

The former Wimbledon runner-up Bartoli will face 39-year-old Japanese Kimiko Date Krumm (1-1) in Saturday's final four. The 12th-seeded Date Krumm wound up capturing this week's three-woman C Group.

The other semifinal will pit Martinez Sanchez (2-0) against 10th-seeded Frenchwoman Aravane Rezai (2-0). Martinez Sanchez was this week's B Group winner, while Rezai wrapped up a D Group win here on Thursday.

Martinez Sanchez toppled second-seeded Aussie Samantha Stosur 7-6 (7-4), 7-5 on Friday. Stosur went 1-1 this week.

In Friday's other round-robin play, fourth-seeded German Sabine Lisicki (1-1) held off eighth-seeded Hungarian Melinda Czink 6-2, 6-7 (1-7), 6-4 and alternate Vera Dushevina (1-0) of Russia, replacing third-seeded Belgian Yanina Wickmayer (1-0) in the field, overcame fifth-seeded Spaniard Anabel Medina Garrigues 2-6, 6-1, 7-5. Czink and Medina Garrigues each went 0-2 for the week.

The surprise U.S. Open semifinalist Wickmayer pulled out of the competition here after learning that she has been suspended for one year by an anti-doping tribunal. The 20-year-old Belgian failed to report her whereabouts to anti- doping officials on three occasions this year.

An undefeated Tournament of Champions titlist this week would earn $200,000.
