Biggest Upsets In Boxing History

[the_truth_1984]

Tyson-Douglas is probably the biggest but here a few fights I would consider upsets as well.

Vince Phillips-Kostya Tszyu
George Foreman-Michael Moorer
Oliver McCall-Lennox Lewis
Hasim Rahman-Lennox Lewis
O'Neil Bell-Jean Marc Mormeck I
Carlos Baldomir-Zab Judah

If you're going by odds, it is the biggest upset in all of sports history. Another huge upset which always flys under the radar was journeyman Willy Salazar stopping unbeaten Danny Romero about 12 years ago on ESPN. That was a shocker.

floyd mayweather jr may 5th, 2007

less of an upset more a close either way decision
i thought mayweather was the right decision though

[Fox McCloud]

How about...

Randy Turpin-Sugar Ray Robinson
Frankie-Randall-Julio Cesar Chavez

The two biggest win streaks in history came to a halt in those two bouts. I don't know how anyone could be more favored than a guy who has won 95 and 93 consecutive bouts respectively.
