MOSCOW (AP) -- Russia's Denis Lebedev stopped Argentina's Victor Emilio Ramirez in the second round to unify the WBA and IBF cruiserweight titles on Saturday.
Lebedev, who came in as the WBA champion, hit Ramirez with hard left uppercuts early in the second round, eventually knocking down the Argentine.
Ramirez beat the count and continued, but within seconds he was overwhelmed by more hammer blow from Lebedev's left, and the referee stepped in to stop the fight.
Lebedev improved to a 29-2 record, while Ramirez dropped to 22-3 with one draw.
The Lebedev-Ramirez fight was elevated to the main event on the card in Moscow after the WBC heavyweight title fight between Deontay Wilder and Alexander Povetkin was postponed following a failed drug test for Povetkin.
