ホルヘ・リナレス
In May 2008, Larios defeated Feider Viloria via fifth-round TKO for the vacant Interim WBC Featherweight title, commissioned when reigning titlist Jorge Linares was unavailable to fight Viloria due to injury. On August 2, 2008 in Zapopan, Jalisco, Larios made his first defense of the WBC interim featherweight title, defeating Marlon Aguilar by seventh round knockout. The bout was competitive for several rounds, but Larious took command of the fight, knocking Aguilar down at the end of the sixth round and knocking him out in the seventh round.
