Last Five Fights: L Timothy Bradley (SD), W Juan Manuel Marquez (MD), W Shane Mosley (UD), W Antonio Margarito (UD), W Joshua Clottey (UD)
Since dropping a unanimous decision to Erik Morales in 2005, Pacquiao had been on the warpath, wiping out Morales in two rematches, defeating Jorge Solis and Marco Antonio Barrera, and scraping past Marquez at super featherweight. Moving up, he stopped at lightweight just long enough to knockout David Diaz for the title before moving up to welterweight to destroy Oscar de la Hoya, Ricky Hatton and Miguel Cotto, among others. Unfortunately, his amazing streak came to an end this past November in controversial fashion in the form of a split-decision loss to Bradley.

Last Five Fights: W Serhiy Fedchenko (UD), L Manny Pacquiao (MD), W Likar Ramos (KO), W Michael Katsidis (TKO), W Juan Diaz (UD)
One of Mexico's finest fighters, Marquez's only losses since 1999 have come at the hands of Pacquiao, Floyd Mayweather Jr. and unbeaten featherweight champion Chris John. With his unique combination of grit and top-tier technique, Marquez overcame age and size to -- in the minds of many -- finally Pacquiao in 2011; however, the judges disagreed. Marquez has won legitimate titles at featherweight, super featherweight, lightweight and super lightweight in his illustrious 19-year career.
