I am not sure whether a tag for a specific sport should be added - but it seems that question is about several sports.

Still some tags to consider could be major-leagues and postseason - although I probably should leave to others to judge whether or not they are suitable.

@Glorfindel Since I did not want to leave many comment related to tagging (and thus not directly to question), I have asked here instead. Since you are active in several chatroom, perhaps it won't bother you that much if I invite you into this room.
