OAKLAND -- The A's welcomed back a familiar presence on Tuesday by naming Sandy Alderson as senior advisor to baseball operations.
Alderson, who most recently served as general manager for the Mets from 2011-18, was the executive who was responsible for assembling the A's three consecutive American League championship teams (1988-90). The '89 club won the World Series by sweeping the Giants in four games.
Alderson served with the A's under different front-office titles from 1981-98. He then became Major League Baseball's executive vice president of baseball operations from 1998-2005 before joining the Padres as chief executive officer from 2005-09.
