There has been no mention of any new rule on pitching, so you'd assume that both teams have everyone available to throw since it'll be 7 days since they last played. The bigger issue is the impact on the next series where Pope, on 9 days rest, will face on of the two teams on one day rest. Clearly a HUGE disadvantage for whichever team advances.
As for the three days rest comment, that's a moot point as GHSA saw fit to completely change all the pitch count rules for playoffs and the only pitch count is no more than 120 pitches in a three day window. That's what allowed Woodstock to throw a pitcher 96 pitches on Wednesday and come back and throw 24 the very next night in a closer appearance.
Add to the mix that rain is in the forecast all week here, who knows when game 3 will be played and subsequently when the championship series might start.
