Coming in to the bout Arroyo has spent more than a year out of the ring, with various issues, but yet will enter the bout as the better favourite with the bookies currently favouring him with odds of 6/10 in favour of the defending champion retaining his title. The champion is the more established fighter, with wins against the likes of Villanueva, Mark Anthony Geraldo and Hernan Marquez, but given his inactivity and the need to fight in the Philippines those odds do look rather stingy.
For those fancying the under-dog Ancajas is priced at generally around 6/4, with those odds have seriously shortened in recently days, but 11/6 is still available. When the bout was announced most had Ancajas at around 2/1 so with the odds shortening and with money going on the "Pretty Boy" it may not be a good decision to wait much longer if you fancy backing him.
At the moment only the "To Win" market is available, however some are carrying the draw which has been price at around 22/1.
