12 rounds at 154. Both were strong, durable, brawling, rough house stylists in the ring.
They both had a very low Ko percentage, but actually,neither Really was a weak puncher.
Rossi brutally ko'd "Duane Thomas", and Baldomir tko'd "Arturo Gatti".
Rossi also out-brawled "Lupe Aquino" and Baldomir overwhelmed "Zab Judah".
They were both Good Solid B grade competitors in the ring. Neither could reach that next level.
Rossi fell short vs Donald Curry,and Baldomir was easily outboxed by Money Mayweather.
In a dream bout hypothetical, I think that this would've been a very entertaining and crowd pleasing brawl of a battle.
I would be picking Rossi to win by a close decision in a gutsy gritty effort. The fans would be clamoring for an immediate rematch. So would Baldomir. I think Rossi would have a very tough fight in his winning effort and would probably prefer to move onto another opponent. Baldomir was No Fun for anyone,except maybe Floyd Money Mayweather.

rosi would do his thing and fiddle around to a ud. id think it wouldnt be that entertaining and that rosi would win clear enough, so no rematch

2 guys who were more effective than they looked. watching either of them, it would make you think you could defo be a world champ boxer if they could

Rossi would definitely win a UD at 154. Baldo might have nicked it at 147

Rosi by wide ud
