Yeah I'm fairly certain he did. Cotto had beaten Mosley and Mosley had looked shit against Mayorga so I see no reason he'd think to cheat after the performance against Cotto if he hadn't already done it before. People cheat because of lack of belief in their own abilities. If he didn't cheat against Cotto in what is considered his best win, then why cheat against Mosley who was inactive and underperforming?
