My DD usually plays third when not pitching. Her secondary training is in her hitting though. I think she would actually rather be looked at for her bat.
DD is only 10 and the OP probably doesn’t care what her secondary position is but:
It seems like since she Ps, which she really wants to do, she is thrown into ever other position except C. Manager fills out the positions and sticks her in whatever is left. She is pretty much the only player that has not had a secondary position on all her Teams.
