The Ukrainian floored his opponent in the 10th round with a flurry
of punches to Peter's head in the 10th round to claim his 55th win in 58 fights
and the 49th by knockout.
Peter, dubbed the Nigerian nightmare, keeled over backwards and
never looked like making the count as the fight came to a dramatic end.
Until then the Nigerian had frustrated Klitscho and the 40,000
crowd at the Eintracht Frankfurt soccer arena without staking a real claim for
the titles.
Peter, who had won 34 of his previous 37 bouts, had never been
counted out before.
"Samuel Peter is a very aggressive boxer. I have great respect
for him and he fought to the last punch," said Klitschko, 34, in the
ringside interview.
Klitschko's brother Vitali holds the WBC title while Briton David
Haye holds the WBA crown.
But with the brothers not fighting each other and Haye repeatedly
refusing a much awaited unification clash with them, any other bout looks like
an inexpensive substitute.
Peter, WBC champion for six months in 2008 before losing to Vitali,
fought Vladimir five years ago and despite knocking the Ukrainian down three
times on that occasion, ended up losing.
This time, he was the second choice for the fight after Russia's
Alexander Povetkin failed to show up for a pre-fight news conference because of
a sinus problem, prompting the IBF to order Klitschko's management to find a
new opponent.
Klitschko controlled the fight from the second round, hurting
the Nigerian with some left-right combinations.
He struck Peter with a vicious uppercut in the sixth round, by
which time the Nigerian already had a swollen right eye.
Klitschko used his jab to wear down his opponent and by the ninth
round, his win looked only a matter of time.
Klitschko finished the fight with one minute and 22 seconds of
the 10th round remaining.
