MINNEAPOLIS -- Terry Ryan's tenure as general manager of the Minnesota Twins is coming to an end.
The 52-year-old Ryan will step down after 12 seasons. The Minneapolis Star Tribune, citing three unnamed sources with the team, first reported the story on its Web site. The Twins have called a news conference for Thursday afternoon to announce a "major" reorganization of their baseball operations.
Team spokesman Mike Herman wouldn't discuss details when reached by The Associated Press, which is also reporting Ryan's ouster.
Longtime assistant GM Bill Smith will succeed Ryan, the Star Tribune reported. Smith has been club vice president/assistant GM for the last 13 of his 22 seasons with the organization.
The Twins won the AL Central title last season -- their fourth division crown in the last six years -- but they are currently 72-74 and out of the playoff chase.
Ryan has long been highly regarded throughout baseball for his work in crafting a contender with a limited payroll. The Twins have received several awards for Organization of the Year this decade, but Ryan began to take some heat this year for the signings of some unproductive veterans and failures to lock up some of the team's stars to long-term contracts.
Assistant general manager Wayne Krivsky, who was long lauded for his behind-the-scenes work as Ryan's right-hand man, left before last season to take over as Cincinnati's general manager.
Krivsky was never replaced, though director of baseball operations Rob Antony added "contracts" to his title earlier this year and became more involved with Smith in negotiating with players' agents.
Twins manager Ron Gardenhire signed an extension last fall that takes his contract through 2009. He was golfing Thursday morning, according to his wife, and didn't immediately return a call from AP.
