Answer
In 2011, Nonito Donaire achieved his peak pound-for-pound ranking, reaching third place by The Ring. This was after he won the WBO super flyweight title in June 2011, and then successfully defended it against Vic Darchinyan in November of that year. Donaire would go on to lose his title in April 2012, but he still remains one of the most popular and successful fighters in the world.
