In May 2004, Márquez fought Lineal & The Ring Featherweight Champion Manny Pacquiao in a bout where Márquez was knocked down three times in the 1st round. Marquez outboxed Pacquiao for the remainder of the bout which was ended in a controversial, split-decision draw. The final scores were 115-110 for Márquez, 115-110 for Pacquiao and 113-113. Judge Burt A. Clements (who scored the bout 113-113) later admitted to making an error on the scorecards, because he had scored the first round as 10-7 in favor of Pacquiao instead of the standard 10-6 for a three-knockdown round
