My good buddy, Drew, recently went to the White Plains, NY card show and met former Oriole and 1960 AL Rookie of the Year, Ron Hansen.
Hansen (b. 1938) played in the majors from 1958 to 1972 for the Orioles, White Sox, Senators, Yankees and Royals. He retired with 1,007 hits, 106 home runs and a .234 batting average. He was with the Orioles he was traded in January 1963 to the White Sox (along with Hoyt Wilhelm, Dave Nicholson and Pete Ward) for Luis Aparicio and Al Smith.
The ball is an OMLB (Selig) ball and as you can see, Hansen inscribed it '1960 AL ROY.' Pretty cool, and I have Drew to thank.
