Ruben Castillo (boxer)

With a record of 42 wins and no previous losses, and 22 knockouts, Castillo received his first world title try: On January 20, 1980, Castillo went up in weight to challenge WBC world Jr. Lightweight champion Alexis Argüello in Tucson. The fight proved to be a close one, with Arguello leading on two judges' cards by only one point and Castillo leading the other card by a single point also, before Arguello knocked Castillo out in round eleven to retain his title.

After the loss to Arguello, Castillo returned to the Featherweight division, winning another fight before receiving his second title try; On April 12 of the same year, Castillo challenged WBC world Featherweight champion Salvador Sánchez in Tucson. Castillo was ahead after six rounds, but ultimately lost a fifteen-round unanimous decision.

Castillo won nine of his next twelve bouts, losing one and drawing (tying) two. This allowed him to keep his ranking as number one challenger by the WBC, and so, on February 20, 1983, he received his third world title try, when he challenged Juan Laporte, who had relieved Sanchez as WBC world champion after Sanchez died in a car accident. This bout was held at Roberto Clemente Coliseum in San Juan, Puerto Rico. He won some of the middle rounds on the judges' scorecards, but Laporte sealed his twelve round unanimous decision victory when he dropped Castillo in round eleven and again in round twelve. The fight was televised live on ABC Wide World of Sports.

Castillo came back to boxing eight months later, knocking Miguel Hernandez out in three rounds at Los Angeles. He won five fights in 1984, including a tenth round knockout victory over Andres Felix and a ten round decision win against Oscar Bejines.

On April 19, 1985, Castillo received his fourth world title try, when he challenged Julio César Chávez for Chávez's WBC world Jr. Lightweight title, as part of a boxing program that also featured Juan Meza's WBC world Super-Bantamweight title defense against Mike Ayala. Castillo once again lost, when Chávez beat him by a sixth round knockout.

His next fight took place in Brazil: trying to keep a privileged ranking among Jr. Lightweights, and to obtain a rematch with Chávez, Castillo lost a ten round decision to Tomas Da Cruz on August 18 in São Paulo. Da Cruz, in turn, lost to Chávez by a third round knockout the following year. Castillo, by his part, fought once more, beating Martin Morado by a ten round decision on March 4, 1986, then announced his first retirement. This retirement lasted three years. In 1989, he made an unsuccessful comeback bid, losing two fights, and requiring hospitalization after being knocked out in the fifth round on August 30 by Edgar Castro. This led to his second retirement from boxing.

Before his second retirement, he had been hired as blow-by-blow analyst by the Western United States television sports channel, ASPN. Castillo called world title fights for this channel, such as the time when Gilberto Roman successfully defended his WBC world Jr. Bantamweight title by defeating Puerto Rican Juan Carazo by a twelve round decision.

After retiring for the second time, Castillo was active as broadcaster for ASPN, analyzing fights in many places across the United States' southwest. He became a popular sportscaster, both among Hispanic and Anglo boxing fans. In 1995, however, ASPN was sold to another network, and Castillo found himself unemployed.

Ruben Castillo made his third comeback as a professional boxer in 1995. On May 24 of that year, he knocked Javier Valardez out in the second round at Bakersfield. The fight was televised nationally on Telemundo, and a small gathering (for a boxing fight) of about 2,000 fans gave him a standing ovation after the fight was over. Telemundo broadcasters said that the ovation proved Castillo's popularity among Bakersfield residents.

He won five fights and lost one (to Fabian Tejada, a well known Argentine boxer of the era), before challenging for the regional, NABO Lightweight title. He won that championship by outpointing Manny Castillo over twelve rounds on September 24, 1996 in Tempe, Arizona. After losing his next bout, a third round knockout defeat against Rudy Zavala, however, Castillo retired for good. He lost to Zavala on March 20, 1997 in Reseda, California. Castillo had a record of 70 wins, 10 losses and 2 draws, with 38 knockout wins as a professional boxer.[4]
