"Tetelo Vargas was a player with exceptional skills in nearly all aspects of the game. He hit for average, had good power for his physique, and was a superb defender. He possessed a strong throwing arm and superior speed – which won him the nickname El Gamo Dominicano, or “The Dominican Deer.” He was an excellent base-stealer as well. His complexion kept him on the wrong side of the major leagues’ color barrier – he was 41 when Jackie Robinson arrived. Yet Vargas accomplished much in more than three decades of professional baseball (1923-1956), a career that took him from his homeland to Puerto Rico, Venezuela, Cuba, Canada and the U.S. Negro Leagues. He is unequivocally recognized as the greatest Dominican player of his era. As Peter Bjarkman, historian of Latin American baseball, wrote, “The slender, wiry outfielder and shortstop. . . is without doubt the most accomplished Dominican native never to spend a single day in the majors.”"
