DAEGU, South Korea - After a sensational Sunday at the athletics world championships, the three fastest high hurdlers of all time take centre stage on the third day of competition in Daegu.

While Monday's action is unlikely to be as dramatic as day two, when Usain Bolt was disqualified from the 100 final and Kenenisa Bekele limped out of the 10,000, another six gold medals are up for grabs.

China's Liu Xiang has returned to form at exactly the right time and will fancy his chances of gold in the 110 hurdles.

The former world and Olympic champion is on a collision course with American David Oliver and Olympic gold medallist Dayron Robles, who both also eased into the semis.

Carmelita Jeter goes for gold in the women's 100, while Allyson Felix can achieve the first part of her double dream in the 400 final.

World titles are also at stake in the men's pole vault and hammer and women's shot put.???
