In an impressive display of raw punching power, the Gatti-eque Subriel Matias (19-1, 19 KOs) of Puerto Rico, blasted out Argentinian Jeremias Ponce (30-1, 20 KOs) in the fifth round, dropping him hard with a beautiful left to the body to win the vacant IBF 140-lb title on Saturday night in the main event in front of a gleeful crowd at The Armory in Minneapolis, Minnesota.
