The Orioles announced Saturday that Andy MacPhail has elected not to return as Baltimore's president of baseball operations.

"On behalf of the Orioles organization, I thank Andy for his service to the club over the last four and a half seasons," said Orioles managing partner Peter Angelos. "Andy's knowledge and experience have helped lay the groundwork for our future success. I hold Andy in the highest regard and thank him for his commitment and dedication to the Orioles."

The Baltimore Sun reported that the 58-year-old MacPhail is leaving the organization to take care of family and personal obligations.

Named to the position on June 20, 2007, he was unable to help a team that is mired in a stretch of 14 straight losing seasons.

During his time with the club, the Orioles went just 307-432 and finished this past season with a mark of 69-93 for a fourth straight finish in last place in the AL East.

MacPhail's father, Lee, spent eight years as general manager of the Orioles from 1958-65 and is a member of baseball's Hall of Fame. Andy's grandfather, Larry MacPhail, is also in the Hall of Fame for his career as a baseball executive.
