Melbourne, Jan 9: Former No. 1-ranked Lleyton Hewitt beat big-serving Canadian Milos Raonic 6-3, 1-6, 7-6 (4) at the Kooyong Classic on Wednesday, progressing to a semifinal against Tomas Berdych.
The 31-year-old Hewitt, who is preparing for his 17th Australian Open, won two years ago at Kooyong, an invitational warmup event for the first major of the season.
Berdych had a 4-6, 6-2, 6-3 win over Croatia's Ivan Dodig, a late replacement for injured Kei Nishikori.
Also, 2009 U.S. Open champion Juan Martin del Potro defeated Paul-Henri Mathieu of France 6-4, 3-6, 7-6 (3) to set up a semifinal against Marcos Baghdatis, who was leading Janko Tipsarevic 6-1, 1-0 when the Serbian player retired with a wrist injury.
