Extra Player In Womens Slow Pitch Softball

Question
Can I use a substitute for an extra player or does the EP have to play the whole game?

Answer
Hi Kellie,

Choosing to play with an EP you're batting 11 (the EP is listed in the BO) and playing defense w/ any 10.  You must now use "a" EP the entire game (11 players) or play shorthanded and take an out in that BP, but you can legally sub in and out for the EP position.
