Ranking Manny Pacquiao's eight division titles

— -- No fighter in history has won world titles in more weight classes than Manny Pacquiao. The Filipino legend has done it in eight divisions, a remarkable feat for a fighter who turned pro at 106 pounds in 1995, won his first title at 112 pounds in 1998 and eventually won a 154-pound belt (even though he weighed only 144.6 for the fight) in 2010.

Pacquiao could have won titles in 10 of boxing's 17 weight classes but he never campaigned at junior bantamweight or bantamweight. Instead he skipped over them and won his second title at junior featherweight.

So as Pacquiao heads into his third fight against Timothy Bradley Jr., a nontitle welterweight bout on Saturday (HBO PPV, 9 p.m. ET) at the MGM Grand Garden Arena in Las Vegas -- in what Pacquiao says could be his final fight -- how do Pacquiao's title victories stack up? I ranked the eight title wins and got Pacquiao's take on each historic victory.
