my daughter plays dizzy dean fastpitch.how many innings can she pitch without being illegal? age 11-14

Dizzy Dean was born here!!! But we play ASA....ASA doesn't have an inning rule but our league does unfortuantly.... Our league has a 4 inning rule which I HATE since I only have one pitcher..... That's when I start having my girls tieing shoes before batting to delay game in the fourth so we don't have to resort to slow pitch!! hehehe Did I say that???? :o
