The odds on Loreto winning are around 1/8, though one bookie has priced the Filipino at 3/16 whilst another has the bout at 1/25. It's obvious that he is the favourite though it's fair to say that their is some variation in the pricing on the Filipino slugger.
As for Itagaki he has been priced at 9/1 to win, though other bookies have got the bout priced at 5/1.
For those who fancy the draw that's available at 25/1.
Sadly the bout doesn't have a "method of victory" market available.
