Germany\'s Sabine Lisicki and Anabel Medina Garrigues of Spain will face off in the semi-finals at the Commonwealth Bank Tournament of Champions on Saturday in Bali. Serbia\'s Ana Ivanovic will play Russian Nadia Petrova in the other semi-final tie in Nusa Dua. The powerful Lisicki served five aces as she saw off Slovakia\'s Daniela Hantuchova on Friday including one serve that was clocked at 203 kilometres (120 miles) an hour. \"It\'s nice when you hit over 200,\" the German said. \"I was just fighting each and every point and enjoying myself. The crowd was very supportive. I\'m glad to be back.\" In the first match of the evening, Garrigues emerged after France\'s Marion Bartoli retired with an achilles injury in the third set. Bartoli won the first set 6-4, and the second went to a nail-biting tie-breaker, with Bartoli failing to win several match points before she succumbed to injury.
