Before the season starts Major League umpires are put into crews, and the crews are scheduled for their games by Major League Baseball. Once the playoffs start individual umpires are selected based on their grades during the season.
Rawlings manufactures the majority of uniforms for teams in Major League Baseball. I do not think that all teams contract Rawlings for uniforms, but I believe that they do have roughly 70% of teams using their uniforms and equipment.
