All three judges ruled that the 37-year-old Klitschko (61-3, 52 KOs) overwhelmed the 34-year-old Povetkin (26-1, 18 KOs) by a score of 119-104.
Bruised and bleeding, the 6-foot-2 Povetkin was floored on three occasions in the seventh round alone.
Although the Ukrainian constantly initiated clinches and held, the 6-foot-6 Klitschko also expertly used his left jab to batter the Russian and land flush shots to the kisser.
Currently ranked fourth in the pound-for-pound rankings, Hayden Panettiere’s boyfriend has now emerged triumphant in 19 consecutive bouts since suffering a TKO at the hands of Lamon Brewster in April 2004.
Even more impressively, “Dr. Steelhammer” has managed to safeguard his titles in 15 straight matches and remains a threat to Joe Louis’ longstanding record of 25 successful defenses.
Without a serious threat looming in a porous division, it’s hard to envision that Klitschko will lose in the near future.
If willing to compete roughly three times annually, expect Wladimir Klitschko to knockout the “Brown Bomber’s” mark at some point in 2016.
