10 Huge Boxing Upsets Nobody Expected To See
6. Manny Pacquiao Defeats Oscar De La Hoya
2008 saw one of the most eagerly anticipated bouts in recent memory come to fruition, as multi-weight champions De La Hoya and Pacquiao clashed.
No titles were on the line despite the success of the pair, but interest was high given Pacquiao's willingness to step up two weight divisions, while De La Hoya moved down in weight to meet the welterweight quota.
Few could have anticipated what would happen in the fight, as the much smaller and seemingly less powerful Pacquiao destroyed the American, winning via eighth round TKO.
De La Hoya couldn't get near the Philippine star, as Pacquiao's movement and hand speed proved too much for the former Olympic gold medallist.
Pacquiao was relentless as he delivered crushing body shots and vicious, quick jabs to the temple of De La Hoya.
Despite many predicting a win for the bigger De La Hoya, he refused to get off his stool at the start of the ninth round, handing Pacquiao the huge upset win.
It proved a defining night for the American as he called time on a brilliant career following the bout.
