Four division world champion Juan Manuel Marquez had a good laugh at the expense of Freddie Roach, the trainer for Manny Pacquiao. Before last Saturday's fourth fight between Marquez and Pacquiao, Roach raised questions about Marquez's new muscular body. Roach said if Marquez's new body "was natural" - then he would "kiss his ass." On Friday, the Nevada State Athletic Commission disclosed the drug test results, indicating that both Pacquiao and Marquez were negative for any banned substabnces. "At the press conference, Freddie Roach said that he would kiss my ass if I came out clean. I am clean athlete," Marquez said. To the critics who said his big right hand shot, that knocked out Pacquiao in the sixth, was a "lucky punch" - Marquez stated the following: "It is a punch that we had worked on for the previous fights [with Pacquiao], but on those occasions Pacquiao had come in with the 1-2 and exit strategy and that's why we didn't have the effectiveness that we had now [with that punch]."
