Appalachian League
On August 28, 2010, Andy MacPhail, then-president of baseball operations for the Baltimore Orioles announced that Baltimore was ending their affiliation with Bluefield and the Appalachian League, effective at the end of the 2010 Appalachian League season. Bluefield's 53 season affiliation with the Orioles, which lasted from 1958 to 2010, had been the oldest continuous affiliation with the same major league franchise in Minor League Baseball.
