From the ages of 12 through 16, he trained to box through the Cuban state government's amateur boxing program. Despite winning the vast majority of his approximately 90 amateur bouts in Cuba, the young fighter could not manage to capture an international title.
Defection from Cuba
At the age of 17, Eliseo Castillo escaped from Cuba on a raft with his brothers Elieser and Eliades and two other friends. The group spent five days at sea before they drifted ashore in Panama. Soon thereafter, they were returned to Guantanamo Bay. After 18 months of processing the group was allowed to emigrate to the United States. He then moved to Miami, Florida.
Professional career
At the age of 20, he began his professional career as a boxer. His first bout was against Anthony Mack on February 24, 1996. Castillo won the bout via first round knockout. He fought off-and-on into the new millennium, at one time even taking 3 years off from the sport. Though his career has been spotty, he still managed to remain undefeated up until April 2005. The only blemish on his record up until that point was a draw to Terry Pitts on November 13, 1998 at the famed Mahi Shrine Temple Auditorium in Miami. Aziz was able to score knockdowns in both the 4th and 5th rounds, but Castillo fought back and secured a majority draw. These fights were at cruiserweight. His biggest victory came on July 3, 2004 against former Heavyweight championMichael Moorer at the American Airlines Arena in Miami. He beat the former champion by a unanimous decision in their 10-round bout. This brought him some level of attention from the boxing press and garnered for him a fight with Wladimir Klitschko the following year. At 2:51 in the fourth round, Klitschko was declared the victor after referee Daniel Van de Wiele stopped the fight. Shortly after the fight with Klitschko, Castillo moved back down to the Cruiserweight division. He has won two straight since the Klitschko loss and was KOd by, the then undefeated, Johnathon Banks on July 26, 2006.
