When in PBP, if you put a player in as, say, a pinch hitter for a pitcher, they get a "P" spot recorded in their fielding stats (albeit with 0s across the board of course). Same thing goes for if you place a player into your lineup at one position and then switch it to another immediately. Very minor cosmetic thing but a small annoyance when viewing fielding stats.

This is most common with double switches... unless there's a way to do it that I'm missing, besides placing the substitute position player into the pitcher slot, the reliever into the other slot, and then switching positions.
