The 34-year-old Lucas Matthysse, of Chubut, Argentina, improved to 38-4 and scored his 35th knockout. The 26-year-old Emmanuel Taylor (20-5, 14 KOs), of Cleverly, Maryland, is now 3-4 in his past seven fights.
Matthysse, suddenly bleeding from a cut around his right eye, floored Taylor with a straight right hand that knocked Taylor to the canvas with around 1:40 to go in the third round. Taylor was able to get up, but could last only two more rounds.
With 57 seconds left in the fifth round, a right-left combination from Matthysse dropped Taylor for the second time in the fight. Taylor was disoriented but was able to reached his feet, but referee Jay Nady decided Taylor shouldn’t continue at 2:21 of the fifth round.
