What is the purpose of teams having spring training patches? Is it for marketing? Hats and jerseys have them, but not pants? Umps don't wear them. Do spring jerseys jerseys get recycled for use the following spring training? Do they go to the minor leagues. I do see that some make it to the collector market. I remember decades ago when actual [season] game jerseys from the previous years (s) were used in spring training. Seems like teams now have jerseys just for spring training only. Are the batting helmets used only for Spring Training?
