Or- maybe the Yankee series is not as important as the Braves series which he would miss if he pitched today...But you are the expert.So no deGrom. Hmmm maybe he needs a break after missing most of the season or maybe it is his 2-4 record against the Yankees in 6 starts. His 3.51 ERA is a full point higher the his career ERA. That might be the real reason.
Though, there is an irrational part of me that really did wish he was pitching today. Only because it just becomes a very fun game to anticipate. Regardless of which NY team you are a fan of.
But it does make more sense to pitch him against the team chasing them
