Doby, the first African-American to play in the American League, was honored Saturday by the Cleveland Post Office at a ceremony held in conjunction with the Jerry Malloy Negro League Conference.
"He's a Hall of Fame center fielder," says Indians executive Bob DiBiasio, "and a Hall of Famer for what he did for society as well."
Melvin Duncan, 83, played with Doby, and said he played through segregation for the love of the game.
"We couldn't go into the hotels," Duncan says, "but we just loved to play baseball."
Doby is only the fourth major leaguer ever to be honored with a stamp.
He joins Ted Williams, Joe DiMaggio, and Willie Stargell.
The stamp is available online through the postal service or at the main post offices in Cleveland, Akron, Elyria, Mentor, and Canton.
