Five keys for Guillermo Rigondeaux

Undefeated, two-time Olympic gold medalist Guillermo Rigondeaux faces the most important battle of his career against fellow 122-pound titlist Nonito Donaire on Saturday in New York.

Rigondeaux (11-0, 8 KOs), from Cuba, is considered one of the best amateur fighters in history. He will look to unify the belts at junior featherweight against a fighter in Donaire (31-1, 20 KOs), who hasn't lost in 12 years and enters with a 30-fight win streak.

Here are five keys to victory for Rigondeaux against Donaire:

Use the force

Watch the hands

Do your jab

Give it a push

Eyes wide open
