Backed with passionate support from the thousands of fans inside the Erzurum Stadium Sports Center, Sipal opened the bout in confident fashion as he aggressively hunted down the talented Russian.
The Champion won the first three rounds on every scorecard, where his excellent hooks and pressure impressed the watching judges.
Zamkovoy enjoyed his best form in the opening stages of the fourth round, but was forced to withdraw from the bout midway through the frame after suffering a head injury.
After Sipal’s control of the majority of the match he was awarded the victory, and wore his belt with pride in the ring along with a replica shirt of his beloved Fenerbahce football team.
Three further fights took place on the undercard, where Onur’s brother Onder Sipal (TUR) defeated Besir Ay (TUR) on points, while Ali Eren Demirezen (TUR) and Batuhan Gozgec (TUR) both picked up victories.
