Robinson's many peers follow his lead

Second baseman a trailblazer for all players of color

Jackie Robinson was the pathfinder to integration in Major League Baseball, yet the entrance ramp after his arrival was not all that congested. The population of black players on big-league clubs was relatively tiny five years after Robinson's debut, and it would be more than 12 years after that historic occasion that every team in the Majors had a black player in uniform.

These pioneers played various positions and came in all sizes and shapes but only one color, the shade that had kept them out of the game for decades. It was truly a color barrier, not one of nationality, so that even such technically Hispanic players as Minnie Minoso (Cuba), Carlos Paula (Puerto Rico) and Ozzie Virgil (Dominican Republic) were finally allowed into the game despite the darkness of their skin.

Robinson began the lengthy procession playing first base for the Brooklyn Dodgers on April 15, 1947. It would be nearly three months later before another team ventured into the territory of integration, with the Cleveland Indians making outfielder Larry Doby the first black player in the American League on July 5, 1947.

Outfielder-third baseman Hank Thompson holds the distinction of helping to integrate two franchises. He made his Major League debut with the St. Louis Browns July 17, 1947. Nearly two years later, July 8, 1949, Thompson and Monte Irvin became the first black players to appear in a game for the New York Giants, for whom they would play major roles on World Series teams in 1951 and 1954.

Irvin's career would eventually take him to the Hall of Fame, as was also the case of Ernie Banks, the first black player for the Chicago Cubs. Sam Jethroe, at 32 with the Boston Braves in 1950 the oldest Rookie of the Year Award winner; Elston Howard, a future MVP with the New York Yankees; and Minoso, the first black player for the Chicago White Sox in 1951; have been under consideration for the Hall by the Veterans Committee for some time, but most of the pioneers were essentially journeymen.

Howard was passed over by his hometown St. Louis Cardinals, who instead in 1954 brought up outfielder Tom Alston, who was out of the game within three years. Bob Trice of the Philadelphia Athletics, Curt Roberts of the Pittsburgh Pirates, Chuck Harmon and Nino Escalera of the Cincinnati Reds and Paula (Washington Senators) all played for fewer than five seasons.

Virgil, the Detroit Tigers' first black player in 1958, played for nine years in the Majors but was primarily a backup catcher. The briefest career of a black pioneer was that of Philadelphia Phillies shortstop John Kennedy, who played in five games in 1957.

The Boston Red Sox were the last team to integrate with the July 21, 1959, appearance of second baseman Pumpsie Green, more than a dozen years after Robinson's entry.
