Editing Acelino Freitas (section)

== Professional career ==

=== Early success ===
After the Pan American Games he turned into a professional boxer on July 14, 1995, against Adriano Jose Soares. With his win by [[knockout]] in the first round that night, Freitas set off a streak of 29 knockout wins in a row, which places as one of the longest knockout wins streak in boxing history. His first 10 wins were against low level competition, but for fight number 11, he took on the much more experienced Edwin Vazquez, knocking him out in the seventh round.

Between 1997 and 1998, Freitas won four more fights and then took on Francisco Tomas Da Cruz, a former world title challenger of [[Julio César Chávez]]. Freitas handled Da Cruz with a knockout in two rounds and then added three more knockout wins before getting his first world title shot.

===First World Title===
On August 7, 1999, Freitas knocked out [[WBO]] Junior Lightweight Champion Anatoly Alexandrov in the first round. Soon after, he signed a contract with [[cable TV]] giant [[Showtime (TV network)|Showtime]], which began to [[television|telecast]] Freitas' fights to the United States. Freitas then made five defenses of his world title and had one non-title bout, all of which ended in knockout wins. He then went to London and took only 45 seconds to stop Daniel Alicea in another non-title affair. Freitas then beat the former world champion: [[Al Kotey]], the brother of [[David Kotei|David 'Poison' Kotei]], by a ten-round decision.

===Freitas vs Casamayor===
On January 12, 2002, Freitas decided to sign for a unification bout with the [[World Boxing Association|WBA]] world champion, [[Joel Casamayor]], a [[Cubans|Cuban]] refugee who resides in [[Florida]]. In a rousing super featherweight unification title bout battle between unbeaten champions, a controversial knockdown and a blatant foul cost Casamayor his unblemished record and his title as Freitas won a close 12 round unanimous decision.

In a classic boxing confrontation between the Brazilian bomber Freitas (129½) and the Cuban boxer Casamayor (129½), the fighters switched roles midway through their encounter in what was reminiscent of [[Ray Leonard|Sugar Ray Leonard]]'s first historic face-off with [[Thomas Hearns|Thomas "Hitman" Hearns]] back in 1981. The scientist Casamayor became the aggressive slugger, while the puncher Freitas turned into the boxer as once again the unpredictable transpired in a mega-fight.

A glancing right-hand to the neck of the off-balanced Casamayor in the 3rd round was ruled a knockdown by referee Joe Cortez and intentionally hitting on the break in the 6th saw the Cuban penalized another point. It was the difference in the finale tallies and the two point cushion that the tiring Freitas retained across the boards on all three judges scorecards. Ring officials Robert Byrd, Bill Graham and Dave Moretti having identical scores of 114 to 112 for the Brazilian.

===After Casamayor===
Next, he went to [[Phoenix, Arizona|Phoenix]], to fight [[Nigeria]]n Daniel Attah, with only the WBO belt on the line, winning a 12-round decision on August 3, 2002. The fight was watched by an estimated 91 million viewers in Brazil.<ref name="They also will meet Acelino Freitas there.

Freitas then retained the title in [[Chicago]] with a fourth-round knockout of Juan Carlos Ramirez. On August 9, 2003, he and [[Jorge Rodrigo Barrios|Jorge Barrios]] engaged in what Showtime commentator [[Steve Albert]] called a ''candidate for fight of the year''. Freitas was floored in rounds eight and eleven, but retaliated with a knockdown of his own towards the end of the eleventh, and ended up retaining the title by knockout in round twelve.

Freitas began 2004 by winning a 12-round unanimous decision over [[Artur Grigorian]] on January 4, to become the WBO's world Lightweight champion. On February 1 of that year, the WBA announced it had named Freitas their 2003 ''Fighter of the year''.

===Freitas vs Corrales===
On August 7, 2004, Freitas lost for the first time, losing his WBO Lightweight title to [[Diego Corrales]] by TKO in the tenth round after being knocked down by a left hook in [[Connecticut]].
