The Red Sox on Wednesday announced a trio of front office promotions, beginning with the promotion of former big league right-hander Brian Bannister to a newly created position: director of pitching analysis and development. He had previously been serving as a pro scout for the Sox. Additionally, amateur scout Chris Mears was bumped to pitching cross-checker, and Gus Quattlebaum was moved up from assistant director of professional/international scouting to director of pro scouting. Quattlebaum will replace former pro scouting director Jared Porter, who reportedly took a job with the Cubs late last month in the wake of Ben Cherington’s resignation.
