Best fight so far i think was Edvaldo Oliveira of Brazil against Carlos Velazquez of Puerto Rico, it was a cracking battle and ended in a draw with Oliveira winning on a count back.
Poorest Performance was probably Oleg Saitov, he looked no where near the Saitov of old who won two gold medals previously...he was getting points scored for nothing against game Miloud Ait Hammi.
Anyone care to add anything else?!
