The decision to play a 3rd game aside I have not seen a ruling (or rule) regarding how the pitching is affected. With the appeals process and span of days since the 2nd game was played I would think at least two different pitching scenarios are possible:
1) enough days have elapsed to reset all pitchers pitch counts so everyone starts fresh and both teams can start their aces in game 3.
2) the 3rd game is treated as if it were being played the day after the double header and all pitch counts for pitchers in game 1 and 2 stand (with the exception of the 8th inning in game 2 that is not official now).
If it is option 1 and both throw their aces, and let's say throw more than 80 pitches each, are either eligible to throw starting Friday in the Finals or do they require 3 days rest?
If this has been addressed I missed it.
