extra hitter

Question
We play by asa rules slow pitch 10 women field can an extra hitter enter the field? can they become a fielder?

Answer
Thanks for the question!

You can bat 11 with the extra hitter but you can only field 10 players on defense at any given time.  You can rotate who plays the 10 defensive spots as often as you like but someone will be riding the pine.

I hope this helps answer your question, if not please reply!
