Manny Pacquiao is 2-0-1 in previous bouts against Juan Manuel Marquez and oddsmakers have the Pacman as a clear favorite to win again. Bettors, however, have been moving toward Marquez in droves this week with the odds on Pacman being bet down from -370 to -260 and the odds on Marquez moving from +280 to +210 in a 24-hour period at the host casino.
With the previous three bouts all being close and controversial, none of the judges from the previous fights have been assigned to this fight. In addition, it an unusual move, all three judges were in attendance at the rules meeting to hear NSAC executive director Keith Kizer explain the scoring criteria to the fighters.
Hall of Fame promoter Bob Arum said Friday that he expects there to be a knockout tonight and a definitive end to the Pacquiao-Marquez series.
