Rigondeaux is in the thick of preparation for his gigantic match with fellow unbeaten fighter Moises Flores on June 17 at the Mandalay Bay Casino and Events Center in Las Vegas, Nevada.
Rigondeaux (17W-0L-0D, 11KOs) and Flores (25W-0L-0D, 17KOs) will fight for the WBA Super World super bantamweight and IBO World super bantamweight belts.
