There's a couple of corrections needed.
First off, Ricardo Amaya was introduced as "Ricardo Maya" so I looked it up and this seems the likely boxer. He was introduced as "Tsunami" which matches the alias.
2nd, Leonardo Torres is listed as both the winner and loser. (Don't you hate it when a fighter beats himself?
)His opponent (and the loser of the fight) should have been Luis Angel Moreno. The outcome is the same, a 4-round decision.
The official DF report came in today and agrees with you.
