Yonnhy Pérez vs. Joseph Agbeko II was a professional boxing match contested on December 11, 2010, for the IBF bantamweight championship.

The tournament originally was scheduled for Leon, Mexico, but Showtime did a site survey and realized that the cost for staging the event there - including security in a region that has been besieged by violence among the drug cartels - would be prohibitive.

When no venue could be secured in Los Angeles, the event was moved to Tacoma, Wash. Pérez was the only current champion, (Vic Darchinyan was the IBO champion, but that organization lacks real recognition by the International Boxing Hall of Fame, other organizations, boxing magazines and fans) while Agbeko had held world titles and Mares was a top contender.

[2] In the opening bout, undefeated, world-ranked rising star Abner Mares of Guadalajara Jalisco, Mexico, faced two-division world champion Vic Darchinyan of Sydney, Australia, by way of Armenia.

[4] Rather than brawling as he had done in his first fight with Pérez, Agbeko chose to use his boxing skills and stiff jab to cruise to a unanimous decision victory, with the judges scoring it 116–112, 117-111 and 115–113.
