Terry W. Ryan (born October 26, 1953 in Janesville, Wisconsin) is an American professional baseball executive and former general manager for the Minnesota Twins of Major League Baseball. Ryan was known for using a low payroll and building up the minor league system to put up contending teams. He resigned as general manager of the Twins on October 1, 2007 but returned to his former post on November 7, 2011 until being relieved of his duties on July 18, 2016. Ryan was hired as a special assignment scout by the Philadelphia Phillies on November 30, 2016.
Ryan attended George S. Parker High School in Janesville, and was drafted in the 35th round by the Minnesota Twins in 1972.
Ryan pitched briefly in the Twins organization in the mid-70s. His playing career started with promise: Ryan posted a 10-0 record and 1.70 ERA in 43 games at Class A Wisconsin Rapids in 1973. However, he subsequently battled injuries and was released by the Twins' AA team in June 1976.
After graduating from the University of Wisconsin–Madison in 1979, with a degree in physical education, Ryan quickly earned respect as an evaluator of talent in baseball. In 1980, the New York Mets hired him as a scout. He spent six seasons as a scout for the Mets before the Twins again showed interest in him. The team hired him as scouting director, a position he held for six years. He was then promoted to vice president and player personnel director under General Manager Andy MacPhail. When MacPhail left for the Chicago Cubs in 1994, Ryan was chosen to replace him.
Ryan's organization relies heavily on constant scouting and analysis of every player in major and minor league baseball. As a result, the team made some startling and at the time questioned acquisitions of players who turned out to be drastically underrated and who became star players in the Twins organization.
