Tomás Molinares

When he returned, on April 15, 1989, he was surprisingly knocked out by the 7–7–2 Horacio Perez, losing his condition as an undefeated boxer. He fought only once more as a professional boxer, suffering an even bigger upset when faced with the debuting Jose Luis Esteven, who also beat the now former world champion by a knockout. Both his two final bouts took place at Barranquilla.

With a record of 23–0, 20 wins by knockout, Molinares flew to the United States to fight WBA world welterweight champion Marlon Starling, who had upset Mark Breland to win the championship. Staged on July 29, 1988, at the Atlantic City Convention Hall in Atlantic City, New Jersey, the bout was scheduled to a limit distance of 12 rounds. The referee was Puerto Rican Joe Cortez.

Larry Hazzard, the New Jersey State Athletic Commission's chairman at the time, thought that Cortez was right in counting Starling out and giving Molinares the win, declaring that the punch may have landed a fraction of a second after the bell but that Molinares threw it before the bell rang (therefore, at first, Hazzard believed that Molinares had won the bout legally). Upon further review, however, Hazzard changed his mind and declared that the commission would not recognize the bout's original result and it would be therefore changed into a no contest. He, however, deferred the decision whether to continue recognizing Molinares as a world champion or not to the WBA. This was reported on the New York Times sports section on August 12, 1988.

A rematch with Simon Ramos, by now 3–9–1, followed, fight in which Molinares again stopped Ramos, this time on September 4, 1987. Next was Molinares' international debut as a professional boxer, when he faced 11–6–3 Fernando Martinez on October 24, 1987, at the Tamiami Fairgrounds Auditorium in Miami, Florida, United States, as part of an undercard that featured a world championship main event for the WBC world Super Flyweight title between Molinares' countryman Sugar Baby Rojas and former world champion, Argentine Gustavo Ballas. Tomas Molinares won his American debut by knocking Martinez out.

Panama's Eduardo Rodriguez had challenged Donald Curry for Curry's undisputed world Welterweight title, beaten Trujillo and lost to Ruben Dario Palacios before he and Molinares had a showdown on Friday, December 18, 1987, as part of an undercard headed by Fidel Bassa's defense of his WBA world Flyweight title against Felix Marti at the Plaza de Toros Cartagena de Indias in Cartagena. Molinares won this test by knocking Rodriguez (20–8 coming in) out. A win over Emiro Oliveros and one against Eric Perea (10–5) followed, both by knockout. Molinares next challenged Marlon Starling for the American's WBA world welterweight title.

Saul Julio, who, at 16–1–1 was considered another top Colombian prospect at the time, next faced Molinares, Molinares coming on top by knockout on January 31, 1986, in Cartagena. On March 14, 1986, Molinares beat Ruben Veliz and then he faced former WBC Fecarbox regional Welterweight champion, Panamanian Carlos Trujillo, who had recently challenged Milton McCrory for McCrory's WBC world welterweight championship; and who was coming off losing to the heralded South African Harold Volbrecht. On April 30, 1986, at Barranquilla, Molinares outpointed Trujillo. By then, Molinares was ranked among the top ten welterweights around the world by the WBA.

A win over mismatched Edgar Rodriguez (1–3 before their bout) followed the Trujillo victory and then, on November 15, 1986, Molinares faced Mexican Sergio Sanchez, 18–7–1, at the Estadio Metropolitano in Barranquilla. This fight was for the Federacion Caribena de Boxeo's (Fecarbox-Caribbean Boxing Federation) vacant welterweight championship. Molinares won the Caribbean area's title by defeating Sanchez with a knockout. Undefeated Jorge Manchengo (8–0) was dispatched next, a technical knockout victim on December 12, 1986. A couple of wins over mismatched Alberto Lindo (3–3) and Maxiliano Cimarra (1–0) (fought at San Andres Island, the first time Molinares boxed as a professional boxer outside of mainland Colombia) followed, and then, on June 19, 1987, Molinares boxed 10–1–1 Eduardo Bautista in Barranquilla, winning by knockout.

Winning the national title was followed by wins over Jairo Segovia, Glenroy Savage and Emilio Olivera, all of whom fell by knockout to Molinares' punches. Then Molinares experienced a raise in opposition quality when he boxed the highly experienced Ezequier "Cocoa" Sanchez, a boxer who had faced some of the very best fighters in the world,before trading gloves with Molinares on December 14, 1985, at the Humberto Perea Coliseum in Barranquilla. Molinares stopped Sanchez, winning the bout by technical knockout.

Tomas Molinares debuted as a professional boxer on October 26, 1984, when he faced 0–1–1 Arnovis Castro at the Bernardo Caraballo Coliseum in Cartagena, winning by decision. On March 1, 1985, Molinares faced the much more experienced Cristobal Torres, who had accumulated a record of 11 wins, 10 losses and 4 draws (ties) in 25 bouts, compared to Molinares' 1–0. He stopped Torres to score his first knockout win as a professional boxer. Wins over Eliseo Benitez and Mateo Valdes followed, and Molinares then challenged for the Colombian national Welterweight title, which was vacant at the time. Molinares fought 3–6–1 Simon Ramos on June 21, 1985, in Cartagena, winning the national championship by knockout.

Molinares started facing trouble to defend his title right away. He reportedly had problems making his division's weight limit of 147 pounds, but on December 16, the Los Angeles Times announced that Molinares would be defending his WBA world championship against former world champion and 1984 Olympic gold medal winner, Mark Breland on February 4. This bout, however, never took place.

Tomas Molinares (born April 6, 1965, in Cartagena, Colombia) is a Colombian retired boxer and former WBA welterweight champion of the world. He is remembered mostly for his fight with Marlon Starling and the controversial way in which it ended. Behind on the scorecards, Molinares launched a punch that knocked Starling out, but the punch seemingly landed just after the bell to end round six rang. Viewings of the fight's video, both by officials during a WBA inquest right after the bout and on YouTube showings, prove and have proven inconclusive as far as whether Molinares threw the punch in time or not.
