Chico Heron

Karl San José Heron (Often given as Carlos Heron.)

During this time, he also played in the Panamanian Professional Baseball League, debuting with Chesterfield in 1957. Heron played the rest of his professional career in Panama with various clubs: Azucareros de Coclé, Chiriquí-Bocas, Ron Santa Clara, Cerveza Balboa, Panalit, and Guardia Nacional. With Azucareros de Coclé, he participated in the 1959 Caribbean Series, where he went 7–for–24 (.292) with two doubles and two runs batted in.

Managerial career Heron managed Chiriquí to its first national championship in Panama's amateur league in 1978. He repeated the feat in 1979. He won another title with Herrera in 1997, and in 2001 as assistant to Aníbal Relúz on the Panamá Metro team.

Heron was a longtime manager of the Panama national baseball team, starting with the 1981 Intercontinental Cup in Edmonton, and the 1981 Bolivarian Games in Barquisimeto, Venezuela (earning a silver medal). He managed Panama to a historic upset over Cuba at the 1982 Central American and Caribbean Games, earning the team a third place finish. Heron managed Panama at various other international tournaments, including the Pan American Games on 1983 (in Venezuela) and 1999 (in Canada).

Under Heron, Panama's second place finish at the 2002 Central American and Caribbean Games was the country's best performance in 64 years. Shortly after, though, Heron's bronze medal at the 2002 Intercontinental Cup was stripped after it was found several Panamanian players (including Roberto Kelly) tested positive for performance-enhancing substances.

As a scout, Heron is best known for discovering future Hall of Famer Mariano Rivera, who signed with the New York Yankees. Heron first saw Rivera play as a shortstop for a Panamanian amateur team and later watched him pitch as a 20-year old in 1990. He subsequently recommended Herb Raybourn sign him, resulting in Rivera signing with the Yankees for a $2,000 bonus. Heron eventually became a mentor for Rivera, who described him as a second father figure. Other major league players scouted by Heron include Mariano's cousin Rubén Rivera, as well as Ramiro Mendoza, Fernando Seguignol, and Rafael Medina.
