The Twins released struggling 2B Bret Boone yesterday, ending a failed experiment to jump-start the team's stagnant offense.

The team also said that gold glove CF Torii Hunter has a broken left ankle that will keep him out at least a month and possibly the rest of the season.

The Twins acquired Boone, 36, in a trade with the Mariners on July 11. But like the rest of Minnesota's offense, Boone struggled in his 14 games with the Twins, hitting just .170 (9 for 53) with three RBI. The team recalled IF Jason Bartlett from Class AAA Rochester to replace Boone.

Hunter had an MRI exam and CT scan yesterday, which revealed a small fracture in his ankle. He was injured in Boston on Friday while trying to make an acrobatic catch by scaling the fence.

* JOB CHANGES: The only general manager the Diamondbacks have had, Joe Garagiola Jr., resigned to become senior vice president of baseball operations in the commissioner's office.

Garagiola will start his new job on Aug. 15, overseeing operations for the major and minor leagues, as well as international baseball. Assistant GM Bob Gebhard will handle Garagiola's former duties while ownership seeks a successor.

Red Sox vice president of baseball operations Mike Port and former big league player Darrell Miller also accepted positions in the commissioner's office.

Port will leave Boston immediately to become vice president of umpiring. Miller was appointed director of the Major League Baseball Urban Youth Academy in Compton, Calif.

Also, Bob Watson was promoted to vice president of rules and on-field operations, and Lou Melendez was promoted to vice president of international baseball operations and administration.

* BREWERS RETAIN YOST: Milwaukee exercised its option for Manager Ned Yost, 49, for 2006. The Brewers are 52-54 this season, Yost's third as manager. He has a 187-242 record overall with Milwaukee.
