Amanda Serrano (30-1-1, 23 KOs) arguably the hardest hitting women in the  modern era of boxing took only 44 seconds to annihilate Hungarian Alexandra Lazar (8-2, 2 KOs) on Tuesday night to claim the vacant WBO female junior featherweight world title during the annual WBO Convention at the Hotel Caribe Hilton in San Juan, Puerto Rico.

The win now makes Serrano a four-division world champion, a feat rarely ever achieved.
