Puerto Rico Baseball League Likewise, Fields represented a good example of a ballplayer who benefited from the opportunities created by the interdependence of Latino and black baseball. Competition in the Caribbean Baseball has always been passionate and intense, as Fields recalled in his autobiography My Life in the Negro Leagues: «Not every could make it down there and you better believe if you didn't produce you didn't last long. I was lucky that way». In addition to eight Negro league campaigns and several minor league stints after integration, Fields also played four seasons in the Puerto Rico Baseball League for the Indios de Mayagüez. He looked forward to supplementing his income during the winter by doing what he loved most.

The previous game, facing the Navegantes del Magallanes of Venezuela, Fields belted a pinch-hit, bottom of the ninth, two-run homer against Terris McDuffie, to lift the Criollos to a 2–1 victory. It was the first walk-off hit of the Series, and rewarded a stellar four-hit by Luis Arroyo, who became the first pitcher born in Puerto Rico to win a Caribbean Series game.
