[ShaneMosleySr]

In addition to what was mentioned:

Quartey-De La Hoya

Vargas-Trinidad

Marquez-Pacquiao fights

Morales-Barrera fights

Jirov-Toney

Tapia-Ayala fights

Ricardo Lopez-Rosendo Alvarez fights

[bballchump11]

Duran vs Hagler

That was my pick also.

[aboutfkntime]

Golovkin. If a lot of people think he won, then it's a pretty good performance in a loss.

he could not even get his game going in EITHER of those fights

that was not even close to Golovkin's best performance

[muslimer12]

Ali in the first Frazier fight

[moltres.]

marquez vs katsidis

loved katsidis after that fight even though he got tko'd.

[killakali]

Which boxer have you seen put in the best performance but ultimately lost?(of all time)

I would say recently Joshua in the first Ruiz fight

Morales vs chino maidana doe

[tritium_arma]

Obviously any robberies.

[SweetSci]

Ike Quartey vs Oscar De La Hoya

[Marchegiano]

Vitali vs Lennox

[SweetPbfAli]

Pacquiao vs. Bradley I

David Tua vs. Ike Ibeabuchi

Gerald McCellan vs. Nigel Benn
