Gennady Golovkin, a Bieber-faced bomber from Kazakhstan, served notice that he may have a sweet smile, but his hands are nasty instruments capable of doing terrific damage to world-class middleweights. Golovkin had Grzegorz Proksa of Poland down three times -- in the first, fourth and fifth (and final) round -- in the main event at Turning Stone Casino in Verona, N.Y.
HBO ran the bout on its "Boxing After Dark" show, and we suspect a few middleweights in the top 20 turned off the tube, admitting to themselves that they want no part of the winner. The Germany-based Golovkin went to 24-0 with 21 KOs, notching knockdowns on a slick boxer who had never been down, as an amateur or pro. Proksa is now 28-2.
