Geoff Huegill last night qualified sixth fastest for the 100m butterfly final at the world championships in Shanghai.

His semi-finals time of 51.85 seconds clocked up against American superstar Michael Phelps' 51.47 seconds.

Huegill is going for gold tonight, but said he would not be underestimating the 14-time Olympic gold medallist, and feels honoured to be able to race him.
