Vargas was among the first ten Puerto Rican ball players to debut in MLB, making his first appearance for Milwaukee on April 17, 1955, the same day as fellow BoricuaRoberto Clemente did it with the Pittsburgh Pirates.[4] Vargas was origianally considered Black and not Puerto Rican, which excluded him from playing in the Majors until Jackie Robinson broke the color barrier.[5]
Sent back to the minors midway through the season, Vargas, who had pitched for the Chicago American Giants of the Negro American League in 1948,[6] performed for 11 teams in eight different leagues in a span of eight seasons from 1949–1960.[7] He played four years in the Mexican League as well as winter baseball at Puerto Rico between 1947 and 1961, while representing his country several times in the Caribbean Series tournament.[8]
Eventually, Vargas had a long career coaching and managing in the Puerto Rico winter league. There, he advised young pitching prospects about the importance of throwing first-pitch strikes and pounding the strike zone and jamming hitters.[9]
