Following his three successful victories over journeymen, Peter took a step up in competition against Nagy Aguilera in an IBF eliminator (Aguilera had earned the position with a stunning first-round knockout of former champion Oleg Maskaev). Peter came in at 237 pounds, the lightest since his seventh pro fight. He dominated an entertaining first round before sending Aguilera down in the second with a right hand counter, Nagy beat the count but was stopped soon after as he was hanging against the ropes, taking heavy shots.
