BUENOS AIRES, ARGENTINA — Marcos Maidana (31-2, 28 KOs) utilized a balanced two-fisted attack to score three knockdowns in route to a decisive fourth round TKO over Petr Petrov (29-2-2, 13 KOs).
After a feel-out first minute, Marcos Maidana established a solid jab and caused Petrov to backpedal due to several grazing straight rights. The shots also drove Petrov to the ropes, where Maidana would land several hooks downstairs before being clinched. In the closing seconds, Petrov was dropped from a straight right.
Maidana pressed his advantage in round two with bullying body punches that forced Petrov to clinch. Those clinches were rewarded by Maidana with right uppercuts. Petrov stood his ground more in round three and gave Maidana pause with occasional right hooks. Maidana responded with a counter left hook that caught Petrov coming in. Maidana did his best work when pinning Petrov against the ropes with heavy hooks mixed to the head and body.
Maidana began the fourth by dropping Petrov to his knees with a straight right. Petrov tried to make a stand, but couldn’t maintain ground in the face of Maidana’s punching power. Again forced to the ropes, Petrov was felled for the last time by a left hook to the body.
The win is Maidana’s first knockout since March 2010, when he also defeated Victor Manuel Cayo with a body shot.
