Career
Joyi, who has fought his entire career in South Africa, made his professional debut on 28 April 2002 in Queenstown. He beat Dalisizwe Komani over the six round distance to make a winning start to his career. Minimumweight world title
The first major fight of his career came on 26 June 2009 in East London, where he fought the Filipino boxer Florante Condes in an IBF Minimumweight title eliminator.
In his next fight, on 26 March 2010 and also in East London, Joyi challenged for the IBF title against the Mexican Raúl García.
Joyi once again gained a unanimous points decision and claimed García"s title, the scores were 119-109 (twice) and 118-110. Joyi appeared to be in full control of the bout until the third round, when an accidental clash of heads opened a deep cut along Takayama"s hairline.
Since four rounds had not been completed, the bout was ruled a no-contest. Joyi then defeated Takayama via a unanimous decision in a direct rematch on 30 March 2012 in East London.
He had reportedly injured his left hand in the second round of that fight.
Joyi’s promoter Branco Milenkovic has planned to stage a unification match. However, two of the other three champions of the four major sanctioning bodies were Japanese. So, they were unavailable until at least June 2012.
In Joyi"s first fight outside of South Africa, he suffered an upset knockout loss at the hands of local fighter Mario Rodriguez (14-6-4) in Sinaloa, Mexico on 1 September 2012.
