Juan Manuel Marquez defeated Orlando Salido by unanimous decision to retain the IBF and WBA featherweight titles in the chief support to the Hopkins-De La Hoya bout in Las Vegas.  Marquez won by scores of 118-110 and 117-111 (twice) and also outlanded Salido 164 punches to 105 according to Punchstat.  Marquez boxed conservatively, content to counterpunch over most of the twelve rounds and fighting toe-to-toe only when Salido forced him to.  The strategy was not popular with the crowd, but it allowed Marquez to advance to a likely rematch with Manny Pacquaio.  In fact, Pacquaio's promoter, Murad Muhammad has just informed Boxingtalk that, "Bob Arum and I have agreed to terms for the rematch to take place early next year; probably the second week of February."  Marquez, now 42-2-1 and rated #2 at 126 pounds by Boxingtalk, fought a thrilling draw with Pacquaio, the generally-recognized world champion, back in May. Salido, rated #8 by  Boxingtalk at 130 pounds, drops 20-9-1, although five of his losses came as a teenager.
