Edwin Rosario was a Puerto Rican boxer who dominated the sport from 1979 to 1997. With a professional record of 47-6 with 40 knockouts, Rosario established himself as one of the greatest boxers of his time. He was posthumously inducted into the International Boxing Hall of Fame in 2006 for his achievements in the ring.

Rosario made his professional boxing debut at the age of 15 on March 3, 1979, defeating Jorge Ortega via 2nd round KO. He went on to win 23 more consecutive fights, which included 20 wins via stoppage. Rosario's exceptional boxing skills, dynamite right hand, and rock-solid chin made him a feared opponent in the ring.

At the age of 20, Rosario had his first world title fight on May 1, 1983, against José Luis Ramírez for the lightweight WBC (vacant) title. He defeated Ramírez via 12 round unanimous decision to become the lightweight champion of the world. Rosario won four world titles at two weight classes, including the WBA lightweight title twice between 1986 and 1990 and the WBA super lightweight title from 1991 to 1992.

Some of Rosario's best fights and notable victories include wins over Livingstone Bramble, Roberto Elizondo, Loreto Garza, Roger Brown, José Luis Ramírez, Juan Nazario, and Javier Cerna. These victories had cemented his legacy as one of the best boxers of his time.

Rosario had a total of six losses in his professional boxing career — five of them in title bouts and one in a non-title bout. He suffered his first loss against José Luis Ramírez via 4th round TKO on November 3, 1984, which ended his 24-fight win streak. He was stopped five times and lost once via decision.

His fighting style was exhilarating, and he was known as "Chapo" ("Shorty") because of his height of 5 ft 6 in (168 cm). Nevertheless, his boxing skills and fighting spirit made him a tough opponent for anyone in the ring. He was an orthodox fighter and had a reach of 66+1⁄2 in (169 cm).

Rosario's career lasted more than 18 years, from 1979 to 1997. His last professional fight was a non-title bout against Harold Bennett at 34 years of age, on September 25, 1997, which he won via 2nd round KO.

Edwin Rosario's record is remarkable and speaks for itself. He had a total of 53 fights during his professional career, with 47 wins and zero draws or no contests. He achieved 40 knockout wins, including five in title fights. He won four world titles and defended his titles three times in his career. He lost six fights in total, five of them in title bouts.

Rosario's death on December 1, 1997, at the age of 34, came as a shock to those who knew him. He was laid to rest in his hometown of Toa Baja, Puerto Rico, where he is fondly remembered by boxing fans and his family.

To sum up, Edwin Rosario was an exceptional boxer, a world champion in two weight classes, and one of the greatest boxers to come out of Puerto Rico. His legacy lives on, and he inspired many boxers, both in Puerto Rico and around the world.
