I mean Ortiz will Ko Amir. What about Maidana, Marcos has proved that he has stamina to fight hard all 12 rounds, i can't say this about Ortiz. However Ortiz has more chances to win over Maidana, and don't forget that Ortiz fights at home and no way Maidana gets decision. Last German based figter from Universum Box Promotion who went fight with Golden Boy Promotion figter to USA was Sturm with ODLH.
