On June 23rd, the IBF ordered its 105-pound interim champion, Maria Baumstarh of Argentina and Yadira Bustillos of Las Vegas to begin negotiations for the rematch bout for the interim title. An agreement was not be reached within the timeframe set forth by the IBF, so the IBF has scheduled a purse bid for August 4th. Kim Clavel of Canada is the current IBF champion in this division. In June, Baumstarh (15-7-1), fighting in her home nation, defeated Bustillos (11-3) by split decision, and the IBF ordered an immediate rematch.
