Fights where much smaller fighter beat a bigger fighter?

[Matt60]

Can you point to me fights where a fighter was clearly smaller by a decent to a bigger fighter and beat him? I was thinking about the Loma-Rigo fight recently and remarked how Rigo looked like a child next to Loma.

Pacquaio versus everyone except Tim Bradley and JMM later in his career

Pacquiao v Margarito was quite a size difference

Not gonna include Pac v Oscar because Oscar was a dead man walking at that weight. Floyd v Oscar at 154 had a visible size difference though.

Dwight Qawi was about 5'7" taking on big LHW and HW.

Harry Greb vs. Gene Tunney

Roy Jones vs. John Ruiz

Spinks vs. Holmes

There's plenty of examples (Tiger-Torres, Hoipkins-Tarver for example) but there's few instances of a great smaller man beating a great bigger man (I don't include Pacquaio-De La Hoya for example as I don't think Oscar is quite great and he was washed up).

Not counting weight drained B.S fights and guys being washed up or one like Marquez-Pacquaio where Pacquaio was bigger in 2012 but both were naturally the same weight basically) I think some examples of a great smaller man beating a great bigger man in (or very near to) their primes

Duran-Leonard I
Pacquaio-Barrera I
Griffith-Benvenutti
Harada-Jofre I & II (I was bogus but II was fair IMO)
Spinks-Holmes

[Gigantes]
