Vitali Klitschko bounced back from his loss to Lennox Lewis with a second-round win over Canada's Kirk Johnson in New York.
Klitschko is keen to get a rematch against Lennox Lewis
Klitschko strengthened his claims for a rematch with the champion with a dominant display in the non-title bout.
The Ukrainian sent Johnson to the canvas with a barrage of blows.
Johnson rose to his feet but looked apprehensive, and his fears proved justified as Klitschko finished him off with a cracking combination.
"Hello Lennox, I know you're watching," said Klitschko after his victory.
"You have been a great champion but I'm ready to beat you."
Klitschko was leading on all three scorecards when a bad cut ended his contest with Lewis in the sixth round last June.
The 32-year-old Ukrainian has called for a rematch ever since against a man scheduled to fight Lewis before a shoulder injury allowed Klitschko to step in.
This bout was billed as a final eliminator for the WBC title still held by the Briton.
Much-hyped Italian-American Joe Mesi retained his unbeaten record but was far from convincing in gaining a majority decision over Monte Barrett on the undercard.
