The Name Game (Shirley Ellis, 1964) ...

[Eastshire]

The rules say you have to list each team member. It doesn't say you can only list team members. So it's a lower limit, not an exact requirement.

There is no rule which prevents bench personnel from being listed in the scorebook.

Around here, it's hit and miss with partners who want to cross out anyone not present/not in uniform..

Edit: And furthermore, the team isn't responsible for what goes in the scorebook anyways. It's only responsible for the list provided to the scorer. Although the argument there is the same: at least all the team members, no upper limit.
