Joshua went into the 2012 London Olympics as a novice on the international scene, despite being a world silver medalist. He received a tough draw in the last 16 of the super heavyweight event in Cuban Erislandy Savón, ranked No. 4 in the world by AIBA and nephew of the three time Olympic champion Félix Savón. The home boxer battled through three tough rounds in his opening contest before being given the result 17:16. This decision caused some controversy with most observers believing Savon had clearly won the bout whilst a few others taking the view that he had won on merit. In his next bout he fought 2008 Beijing Olympics silver medalist Zhang Zhilei, dropping his taller opponent in the middle round; Joshua won by 15:11 guaranteeing at least a bronze medal. In the semi-final Joshua met Kazakh boxer Ivan Dychko, and despite Joshua's height disadvantage he won by 13:11 victory gaining a place in the Olympic final. Joshua met 32-year-old reigning Olympic Champion and former twice World Champion, Roberto Cammarelle of Italy in the closing bout. After conceding the first two rounds (6:5 and 13:10) to Cammarelle, an adversary he had already beaten the previous year, Joshua grew into the fight and fought back to level the scores after the third round (18:18). Joshua was announced winner via count-back and the new Olympic champion. The final decision was criticised by some boxing experts, being defined as a "home decision".
