Ricards Bolotniks: The Hidden Latvian Assassin-The Riga Road Warrior-The Fly In The Ointment.

He is good to watch like Bolotņiks too. Win they or loss, they aren't boring.

Interestingly that biggest upset Bolotņiks had delivered I think was fight vs Cordoba in Spain.
Bolotņiks before this fight had 9-3-1 ( 3KOs ) pro record that looked worse than Cordoba 11-1-0 ( 9KOs) record.
Cordoba does come from KB and he was not bad KBer. In pro boxing he mainly fought nobodies but he can crack and had 1 relatively impressive win: Cordoba had stopped in fight for Spanish Cruiser tittle Ibrahim Lopez.
Lopez then had 9-1-1 ( 6KOs) record and best his win in resume was in fight vs Luis Rodriguez for Spanish Cruiser tittle when he stopped in distance Rodriguez ( 7-1-0).
Lopez wasn't pillow fisted. Cordoba stopped him and Lopez after this didn't had pro boxing fights.

There some supposedly "pillow fisted" Bolotņiks ( only 3KO wins in 13 fights ) and big upset: Bolotņiks stopped Cordoba in 1 st round.
