Offense Only terminology

[CecilOne]

I think we had a consensus on this, but can't search for 2 letters as a key.

When the DP is playing the field, some other batter is then not in the field, just batting. That other batter should be noted on the lineup for reference.

NCAA uses OP for that (Offense Player, although all the batters are).

USA, NFHS, etc. have nothing defined; so do we
- use OP , Offense Player, as NCAA for consistency
- use OO for the more specific Offense Only

I need something for teaching purposes, USA, NFHS.
