Argentinian Lucas Bastida (22-3-1) stopped Ukrainian, based in Latvia, Bohdan Sobol (18-1) 30 seconds into the eighth round of their middleweight bout in Riga, Latvia.
Basitida was the sharper puncher of the two and floored Sobol in the second. Sohol, however, came back afterwards and seemed to gain control in the fourth and fifth, working well behind the jab as Basilda appeared to have punched himself out.
But the tide turned again in the sixth as Sohol kept walking into sharp counters and a bad swelling around the right didn't help.
Early in the eighth, Bastida really hurt his opponent with a left hook and followed with a barrage of punches - Sohol was knocked down and was out of it. It was a bad knockout and while Sohol regained consciousness he was very unsteady and was dragged out of the ring - hopefully to be put on a stretcher - while Bastida and his team celebrated.
On the undercard Estonian cruiser Stiven Aas outscored Latvian veteran Reinis Porozovs in a three round professional boxing match. Porozovs was down in the final round and that sealed his fate.
Latvian light heavy champ Juris Zandovskis outscored Pole Maksymilian Kapcpdzyk in another three-roudner.
