They would only get Nola/Wheeler once.
The winner of the Wild Card series does not have much rest for the LDS.
This was the whole big deal about DeGrom and Scherzer. They can be used in the Wild Card round, but only each once in the LDS. Whereas if they had won the division, they would have been able to use at least one of them twice in the LDS.
Game 1 - Degrom
Game 2 - Scherzer
Day Off
Game 3 - Bassitt
Game 4 - Walker
Game 5 - DeGrom
But because they're lining both up for the the Wild Card Series it'd look like this:
WC
Game 1 Degrom
Game 2 Scherzer
Game 3 (Sunday)
Monday Off
LDS
Game 1 - Tuesday
So Degrom and Scherzer would be used Games 2 and 3, and only getting one start each on full rest. If we face Wheeler or Nola, we'd only see them once unless Philly put Game 2 starter on 3 days rest.
