Rodney died of age-related causes Sunday at his home in a retirement community in Walnut Creek, Calif., said his daughter, Amy Rodney.
Jackie Robinson suited up with the Brooklyn Dodgers and broke baseball's color barrier in 1947, Rodney began pressing for the desegregation of baseball via columns and stories in the Daily Worker's sports pages.
He called the ban against blacks in the major leagues "un-American" and "the crime of the big leagues."
"None of the mainstream papers in the `30s made anything out of the fact that in the land of the free, midway through the 20th century, a great athlete with the wrong pigmentation of his skin couldn't play in our national pastime," Rodney said in a 2005 interview with the San Francisco Chronicle.
When a sports reporter asked Joe DiMaggio who was the best pitcher he had ever faced, the Yankee power hitter unhesitatingly responded by saying, "Satchel Paige." (DiMaggio had faced the great Negro League pitcher in postseason exhibition games.)
While other newspapers ignored DiMaggio's comment, Rodney ran a big headline over the story in the Daily Worker the next day: "Paige the Greatest I Have Faced -- DiMaggio."
Rodney also reported Brooklyn Dodgers manager http:// Leo Durocher’s %20 admission to him that the Dodgers would sign black players "in a minute, if I got permission from the big shots."
In his columns, Rodney pressured club owners and baseball commissioner Kenesaw Mountain Landis to end baseball's color barrier.
Rodney and the Daily Worker's campaign to induce the major leagues to integrate baseball included launching petition drives targeting baseball owners and executives and organizing informational picket lines at ballparks.
Through it all, Rodney, the communist, was shunned by some of his fellow sportswriters.
He also had to use pseudonyms to publish two baseball books for children in the early 1950s: "The First Book of Baseball," under the name Benjamin Brewster; and "The Real Book About Baseball," under the name Lyman Hopkins.
For decades, Rodney was considered little more than a historical footnote, a man whose efforts to help break the color ban in baseball was forgotten because he was a communist.
But that changed in 1997 when he was invited to speak at a national conference at Long Island University in Brooklyn celebrating the 50th anniversary of Robinson's debut as a Dodger.
The same year saw the publication of "Jackie Robinson: A Biography," by Arnold Rampersad, who wrote that "the most vigorous efforts [to integrate baseball] came from the Communist press . . . an unrelenting pressure for about 10 years in the Daily Worker, notably from Lester Rodney."
Rodney went on to be invited to speak at baseball symposiums and was frequently interviewed.
He also was the subject of a 2003 biography by Irwin Silber: "Press Box Red: The Story of Lester Rodney, the Communist Who Helped Break the Color Line in American Sports."
In 2005, Rodney was inducted into the Shrine of the Eternals by the Baseball Reliquary, a nonprofit educational organization in Pasadena.
Rodney "was a very early voice in the American journalistic community to talk on a regular basis for the need for major league baseball to integrate and include African Americans playing side by side with Caucasian players," Terry Cannon, the organization's founder, told The Times this week.
