Norman Leroy Siebern was an American professional baseball player and scout. He appeared in 1,406 games over a 12-year career in Major League Baseball as a first baseman and left fielder for the New York Yankees, Kansas City Athletics, Baltimore Orioles, California Angels, San Francisco Giants and Boston Red Sox between 1956 and 1968. A two-time World Series champion and four-time American League All-Star, his best season came in 1962 with the Athletics when he hit 25 home runs, with 117 runs batted in and a .308 batting average. He might be most remembered, however, as being one of the players the Yankees traded for Roger Maris on December 11, 1959.
