Rule reference for 2018 March Clarification

[Zepp]

I agree. The exception to Rule 4-6-D during Pool play allows any player to replace the injured player. I wish they had added the phrase "...to complete her base running responsibilities."

I remember when USA softball (ASA at the time), first tinkered with Roster batting and it was a disaster with line-up card management in regards to
keeping track of EP's playing defense for a starter and keeping track of entry & re-entry even though everyone was already in the line up to bat.
They corrected that at the end of the summer with a Rules Clarification.

I'm getting a sense of deja vu all over again with the OP

All the other clarifications on the March 2018 clarification document seemed to fall in line with the new rules.
The OP was the only one I couldn't find any supporting evidence in the rules book.
