CHICAGO (AP) The Chicago Cubs shook up their player-development operation, with Matt Dorey taking over as senior vice president of player development and directors of pitching and hitting being appointed.

Dorey, Chicago's director of amateur scouting the past six years, was previously a scout for the Boston Red Sox and a college coach.

Former major league reliever Craig Breslow has been appointed director of pitching and special assistant to the president and general manager. Hired in January as director of strategic initiatives for baseball operations, he will try to develop more homegrown impact pitchers.
