Navarro, 105, was hospitalized on Wednesday in Ponce after having a heart attack, and died surrounded by relatives, according to a statement released by his family.
Navarro played shortstop and second base for the Cuban Stars in the Eastern Colored League from 1928-29. He also co-founded the Ponce Lions, which is still in existence. In addition, he was the first Puerto Rican to play in the Negro Leagues.
In 1992, Navarro was elected to the Puerto Rico Baseball Hall of Fame, and he was enshrined in the Puerto Rican Sports Hall of Fame in 2004.
Before the start of the 2008 First-Year Player Draft, Major League Baseball held a ceremonial draft of former Negro League players, during which the Yankees drafted Navarro.
