Spence vs Peterson results: Adam Kownacki stops Iago Kiladze in six

Popular Polish-American heavyweight Adam Kownacki kept his undefeated record tonight, stopping Iago Kiladze in the sixth round of their heavyweight fight at Barclays Center in Brooklyn.

Kownacki (17-0, 14 KO) came into this fight nearly 20 pounds heavier than he was in his last outing, a career-best win over Artur Szpilka, and Kiladze (26-2, 18 KO) tried to take advantage of that, targeting the body and moving around a lot in the first couple of rounds. He bloodied Kownacki’s nose in the opening frame and seemed to have a good approach.

But Kiladze, a 31-year-old fighter from Georgia, now fighting out of Freddie Roach’s Los Angeles gym, appeared to tire quite dramatically by the third round, as his legs just started slowing down, forcing him to clinch more than move, which put him in Kownacki’s wheelhouse.

Kownacki, 28, dropped Kiladze 30 seconds into the fourth round on a right hand, but replays did show that Kiladze’s left foot was stepped on with the punch, tripping him up a bit. That said, Kiladze, despite his protests, fought like a guy who’d been stung and dropped from there on.

Kownacki did more solid work in the fifth, then in the sixth, landed two uppercuts and another right hand that sent Kiladze stumbling back and down to the canvas. Kiladze did get up, but the fight was rightly stopped there.
