OSTRAVA — World and Olympic champion Sally Pearson will compete in her first 100 meters hurdles event since winning gold at last year's London Games when she races in the Czech Republic next week, Athletics Australia said Thursday. The 26-year-old will compete in Ostrava next Thursday before taking part in the hurdles at the IAAF Diamond League in Birmingham on June 30, it said on its website (www.athletics.com.au). Pearson suffered a grade-one hamstring tear in a 4x100m relay at the Asian Grand Prix meet in Sri Lanka last month after missing the domestic season with the same injury. The Queenslander will defend her world championship title in Moscow in August. —Reuters
