O's have hired John "T-Bone" Shelby to fill the 1st base coach slot vacated by Sam Mejias.
per Jeff Zrbiec...Orioles manager Dave Trembley today hired John Shelby to be the team's first base coach, calling on the organization's successful past to fill one of two remaining vacancies on his staff.
Shelby becomes the third new addition to the Orioles coaching staff since Opening Day 2007, and there will be a fourth when Trembley decides on a bench coach to replace Tom Trebelhorn, who was not asked back for another season.
