Was the Fix in to make Pacquiao lose?

The UKTelegraph report that outside experts all said MP won. But the Vancouver Sun quotes a guy who says what a lot of folks are thinking:

Canadian poker player and sports analyst Haralabos Voulgaris noted that there was a late surge of bets on Bradley. "Late money on this boxing match, Pac was -432 at 2pm it closed -397 at pinny. Lots of late money on Bradley."
