WBO #1 ranked heavyweight Alexander "Sascha" Dimitrenko (29-0, 19 KOs) scored an impressive third round knockout over former world title challenger Luan Krasniqi (30-4-1, 14 KOs) on Saturday night at the Burg-Wächter Castello in Düsseldorf, Germany. Coming back from a loss to Tony Thompson in a WBO eliminator 16 months ago, the 37-year-old Krasniqi knowing this is likely his last chance, took the fight to the 6'8 Dimitrenko and won the first two rounds. However in round three, the powerful 26-year-old Dimitrenko landed a crushing left hook to the body and Krasnigi collasped painfully to one knee for the full count. Time was 2:54. Dimitrenko retained his WBO Intercontinental belt and remained on a collision course with his Ukrainian countryman WBO champion Wladimir Klitschko.
