American Shadasia Green proved she is a threat at super middleweight and knocked out former world champion Elin Cederroos in the sixth round to become the new World Boxing Association (WBA) Continental Americas champion at 168 pounds. 

A devastating performance against a big opponent was confirmation that Green is for big things and would be a candidate for a world title fight in the short term. 

Green knocked down Cederroos in the third round to give a first warning of her power and knew how to handle all the rounds with good exchanges to end up forcing the referee to stop the actions in the sixth round.

Green remains undefeated after 12 fights, 11 of them won by knockout. Cederroos now has 8 wins, 2 losses and 4 knockouts.
