James William "Junior" Gilliam was an American second baseman, third baseman, and coach in Negro league and Major League Baseball who spent his entire major league career with the Brooklyn / Los Angeles Dodgers. He was named the 1953 National League Rookie of the Year, and was a key member of ten National League championship teams from 1953 to 1978. As the Dodgers' leadoff hitter for most of the 1950s, he scored over 100 runs in each of his first four seasons and led the National League in triples in 1953 and walks in 1959. Upon retirement, he became one of the first African-American coaches in the major leagues.

The Los Angeles Dodgers are an American professional baseball team based in Los Angeles. The Dodgers compete in Major League Baseball (MLB) as a member club of the National League (NL) West Division. Established in 1883 in the city of Brooklyn, which in 1898 became a borough of New York City, the team joined the NL in 1890 as the Brooklyn Bridegrooms and assumed several other monikers before finally settling on the name Dodgers in 1932. From the 1940s through the mid-1950s, the Dodgers developed a fierce crosstown rivalry with the New York Yankees as the two clubs faced each other in the World Series seven times, with the Dodgers losing the first five matchups before defeating them to win the franchise's first title in 1955. It was also during this period that the Dodgers made history by breaking the baseball color line in 1947 with the debut of Jackie Robinson, the first African American to play in the Major Leagues since 1884. Another major milestone was reached in 1956 when Don Newcombe became the first player ever to win both the Cy Young Award and the NL MVP in the same season.
