Hewitt beats Raonic, del Potro advances at Kooyong
The 31-year-old Hewitt is preparing for his 17th Australian Open. He won two years ago at Kooyong, an invitational warm-up event for the first major of the season.
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 retired with a wrist injury.
