Signed as an amateur free agent in 1955, Brooks Robinson debuted that year in Baltimore as an 18-year old.  It was clear from the beginning that he was a wizard with the glove, but it took him some time to develop his hitting game.  In 1960, he did that, and throughout the decade and beyond, he was considered the best Third Baseman in the game.

Playing his entire Major League career with the Baltimore Orioles, Jim Palmer overcame a lot of early arm trouble to become one of the best hurlers in the 1970s.

The selection of Cal Ropken Jr. at the top was straightforward.

Cal Ripken Jr. is without question the greatest Baltimore Oriole ever, and also one of the best baseball players that existed.

A two-time All-Star with the Chicago Bulls, Luol Deng was born in Sudan, moved to England as a child, and immigrated to the United States as a teen.  It was the latter move that allowed him to hone in skills in the game of basketball, and become the best player to come out of what is now South Sudan.
