The 1950s were viewed as a time of tribulation for the Red Sox. After Williams returned from the Korean War in 1953, many of the best players from the late 1940s had retired or been traded. The stark contrast in the team led critics to call the Red Sox' daily lineup "Ted Williams and the Seven Dwarfs." Jackie Robinson was even worked out by the team at Fenway Park, however, owner Tom Yawkey did not want an African American player on his team. Willie Mays also tried out for Boston and was highly praised by team scouts. In 1955, Frank Malzone debuted at third base and Ted Williams hit .388 at the age of 38 in 1957, but there was little else for Boston fans to root for. Williams retired at the end of the 1960 season, famously hitting a home run in his final at-bat as memorialized in the John Updike story "Hub fans bid Kid adieu." The Red Sox finally became the last Major League team to field an African American player when they promoted infielder Pumpsie Green from their AAA farm team in 1959.
