Félix Trinidad vs. Ricardo Mayorga, billed as "Back with a Vengeance", was a professional boxing match contested on October 2, 2004.

[1] It pitting together former world champions Felix Tito Trinidad and Ricardo Mayorga, under the promotion of Don King, at the Madison Square Garden in New York City, United States.

The behind the scenes storylines involving this fight helped build up fan interest too: Mayorga, nicknamed "El Matador" ("The Killer"), had been active for the two previous years, settling for a no contest and a knockout win (in a rematch) against Andrew Lewis, then defeating Vernon Forrest twice before losing to Cory Spinks, all in world title fights.

Because of those circumstances, many experts predicted that this fight would be like the fight between Joe Louis and Rocky Marciano or the one between Larry Holmes and Muhammad Ali: A former great who had been out of the ring for a considerable amount of time taking on an opponent who was, on the other hand, very good, but not to be considered as good as the retired champion ever was, therefore, many predicted Trinidad's doom at the hands of a man like Mayorga, who had won a world title and proven himself against some of the best boxers available while Trinidad was away from boxing.

The fight was telecast on HBO's Pay Per View, and commented by Jim Lampley, Larry Merchant and Roy Jones Jr.

A famous part of this round sees Mayorga drop his hands sticking his chin in the air daring the vicious puncher Trinidad to try his best.

Mayorga struck in round three with a right to the chin, that caused Trinidad to reel back and touch his glove to the mat.

[citation needed] On October 5, he announced his retirement from boxing, although he later returned onto the ring to fight Michele Piccirillo and then Oscar De La Hoya.
