Identifying "playing position" of Sprite

Hey guys

Having a little difficulty here with my sports sim game working out how to identify the position that the player currently is in.

The image above shows a simple rotation in the volleyball game which happens after the serve has been won

The idea is to assign a value which is the players current position (because the positions which the players move to and also the actions which they are performed are determined by which position they are currently in) but I am not sure exactly how to go about this. I also need to identify the players current position to assign the statistics to the player which is currently in that position at that time

Hope that makes sense and someone has a bright idea!

Is it as easy as assigning a script with a variable attached to the player sprites that gives the players position and access it from the main script?
