By John Salvado Rising American superstar Xavier Carter and former 100m world record holder Asafa Powell will put a world-class gloss on the sprints in the upcoming grand prix meets in Sydney and Melbourne.

Carter, known as the X-Man for his crossed-arms victory salute, burst to prominence when he clocked 19.63 seconds in the 200m in Lausanne in 2006. At the time it was the second quickest half-lap race ever run behind Michael Johnson's 19.32, although Usain Bolt lowered the world record to 19.30 at the Beijing Olympics. Carter will contest the 400m at the Sydney Track Classic on February 28 and the 200m at the World Athletics Tour meet in Melbourne five days later. The 23-year-old is back to full fitness after battling knee injuries in 2007 and 2008. "After being injured this past summer I wanted to get back on track as fast as possible," said Carter. "I have heard so many great things about the meets in Australia that I thought that there was no better place to start my outdoor season." Powell will continue his love affair with Australia, having previously competed down under in 2006 and 2008. View complete article at ninemsn.com.au
