In March 2010, Valero vacated his WBC title in order to compete in the light welterweight division. Valero was able to continue the fight and went on to win by corner retirement when DeMarco failed to answer the bell for the tenth round. In the second round, Valero suffered a serious cut over his right eye after DeMarco landed an unintentional elbow. Valero's second and final defense of the belt came against Antonio DeMarco in Mexico, on 6 February 2010. Valero's next fight came on his home turf of Venezuela, in La Guaira, where he successfully defended his WBC lightweight title by a TKO victory over Hector Velasquez in the seventh round. Pitalua managed to get up but suffered two more knockdowns before the referee stopped the fight at 0:49 of round two.

After an uneventful first round, Valero knocked Pitalua down just seconds into the second round with a right hook. Pitalua came into the fight with 14 consecutive knockouts on his 46–3 record, and with Valero's 24 consecutive knockouts the stage was set for a decisive match between two heavy hitters. The bout marked the first time Valero had fought in the United States since 2003. He fought Antonio Pitalua for the vacant WBC lightweight title on 4 April 2009, in Austin, Texas. On 3 September 2008, Valero vacated his WBA title to fight in the lightweight division. Valero would go on to successfully defend the title four times before moving up in weight class, with his final defense a seventh-round stoppage of Takehiro Shimada in Tokyo on 12 June 2008. Deciding Mosquera had received enough punishment, the referee called a halt to the match at 2:00 of round ten, making the 24-year-old Valero champion. The answer came after ten grueling rounds when the ever-tenacious Mosquera finally started to wane under the challenger's continuous heavy-handed counters. At this point in his 19–0 career, Valero's longest fight had only been two rounds, and the question remained as to whether the untested Valero had the stamina to go the distance.

However, Mosquera recovered and in the third round responded by knocking Valero down, which was to be Valero's only knockdown in his career. In what would arguably prove to be both boxers' toughest contest, Valero started out the match in signature fashion, knocking down the champion twice in the first round. In his first attempt at a world title, on 5 August 2006, Valero faced WBA super featherweight champion Vicente Mosquera.

The Los Angeles local cable show also aired Valero's workouts, sparring sessions and interviews conducted by Palmiere. His biggest backers in the sport included Doug Fischer of The Ring magazine (who, on the former boxing website he used to write for,, regularly covered Valero in his articles for the website, which also aired videos of his workouts and sparring sessions) and Boxing Inside with journalist Peter Palmiere. īecause of his punching power and perfect knockout ratio, Valero became a cult sensation in the community. That record has since been broken by Tyrone Brunson, but most boxing experts do not acknowledge Brunson's claim owing to the extremely poor level of opposition he faced while making his way to the record in contrast to Valero's opponents, just one of Brunson's 19 opponents had a winning record and six had failed to win a single fight in their careers. On 25 February 2006, Valero set a new world record by winning his first 18 fights as a professional by first-round knockout, breaking Arthur Susskind's historic record set in 1905. In 2010, Valero died by suicide in jail after being arrested on suspicion of killing his wife. A southpaw known for his highly aggressive fighting style and exceptional punching power, Valero remains the only champion in WBC history to win every fight in his career by knockout. He was an undefeated former world champion in two weight classes, having held the WBA super featherweight title from 2006 to 2008 and the WBC lightweight title from 2009 to 2010. Edwin Valero (3 December 1981 – 19 April 2010) was a Venezuelan professional boxer who competed from 2002 to 2010.
