32-year-old Otto Wallin, who is ranked number four in the WBO world rankings, outplayed his opponent in the first five rounds but in the sixth round Olgiun landed a punch that caused a bleeding wound over Wallin's left eye, fightnews reports .com
Wallin then took over in the last two rounds and won the match with clear judges' numbers.
"Olguin fought bravely but was not enough against Otto, who boxed with a significantly higher quality.
Otto boxed aggressively and the longer the match went on, the more his fitness and skill took their toll," writes Wallin's team in a press release.
The win in New Hampshire is the 25th of Wallin's pro career.
