Before the 1966 season, Frank Robinson was traded to Baltimore from the Cincinnati Reds.  With Cincinnati, Robinson was a Rookie of the Year, MVP, and had five 30 Home Run seasons.  Despite this success, the Reds owner, Bill DeWitt, engineered trading him to Baltimore for Jack Baldschun, Milt Pappas, and Dick Simpson.  DeWitt defended his decision, calling Robinson an "old 30."  The legendary outfielder would respond with the greatest season of his career and put the Orioles on the map for good.

Mike Mussina played his first ten years in baseball (1991-00) with the Baltimore Orioles, and by his second season, the former USC Trojan was one of the better Pitchers in the American League. 

It takes a special kind of player to hit 3,000 Hits and 500 Home Runs over a career.  Eddie Murray was just that. 

At one time, we are going to do the greatest players of defunct/relocated teams.  When we get to the St. Louis Browns, it will be without question, George Sisler.  As the Browns relocated to Baltimore to become the Orioles, Sisler has his spot here, and we will have quite a few players on this list that never played professionally in Baltimore.
