WBA middleweight champion Felix Sturm (32-2-1, 14 KOs) simply outclassed Koji Sato (14-1, 13 KOs) getting a seventh round referee’s stoppage after dealing Sato a brutal beating on Saturday night at the KönigPALAST in Krefeld, Germany. Sturm was extremely sharp with his jab early on while fending off Sato’s powerful attacks. As the bout progressed, it almost seemed Sturm couldn’t miss as he schooled the previously unbeaten challenger. Referee Luis Pabon finally steped in to stop the carnage at 2:46 of round seven. It was Sturm’s sixth title defense.

WBO super middleweight champion Karoly Balzsay (21-0, 15 KOs) successfully defended his title with an eleventh round knockout over former middleweight champion Maselino Masoe (29-6, 27 KOs). It was a left-right combination that sent the 42-year-old Masoe to the deck where he was counted out by referee Mark Nelson. It was the unbeaten Balzsay’s first title defense. Time was 2:07.

Unbeaten middleweight Gennady Golovkin (16-0, 13 KOs) dropped Anthony Greenidge (13-3-1, 5 KOs) twice in round one and finished him at :49 of round five.
