MINNEAPOLIS (AP) The Minnesota Twins have fired general manager Terry Ryan.

The Twins entered the day 33-58, 21 games out of first place in the American League Central Division. Only Atlanta has a worse record in the majors.

Assistant GM Rob Antony will take over on an interim basis. Owner and CEO Jim Pohlad made the announcement Monday, hours before the Twins opened a series in Detroit.
