A lot of books seem to just have the big boxing fights or they are inconsistent with the lesser bouts at least. ProBoxingOdds.com shows Ladbrokes had a full array of props for Caballero/Ruiz. I use a local bookie sometimes or DirectBet to take advantage of slow moving lines or for the occasional props that are better priced and horribly juiced live lines that are available.
i saw ladbrokes but they dont service my country. you are lucky if your local bookie does props on such an obsure fight. like i mentioned before, pinnacle didnt offer either fight. because i had no access to the caballero props i ended betting on ruiz and lost when my main play wouldve been the over or caballero decision.
