MASHANTUCKET, Conn. - Powerful World Boxing Association & International Boxing Organization World middleweight champion Gennady "GGG" Golovkin (27-0, 24 KOs) stopped challenger Matthew "Mack The Knife" Macklin (29-5, 20 KOs) with a lethal body shot in the third round, headlining tonight's HBO Triple-Header, presented by K2 Promotions and DiBella Entertainment, in the MGM Grand Theater at Foxwoods Resort Casino.

Golovkin stalked the game Irishman and finished the fight at 1:22 of the third round with a vicious left hook to Macklin's ribs, sending a strong signal to the entire 160-pound division that the Kazakh is a true force.

"I was in perfect position for that body shot," Golovkin commented. "I want this fight (vs. Sergio Martinez).  I felt great in the ring, he never hurt me.  It was an easy fight for me.  I want to fight again soon.  Any top fighter, any champion, any belt holder....anywhere."
