The Philadelphia Phillies have had one of the best starting rotations in all of baseball this season. With Zack Wheeler, Aaron Nola, Cristopher Sánchez, Ranger Suárez and Jesús Luzardo anchoring the starting five, there haven't been many others that could match up to that.

Now into September, that plan appears to have come to fruition. However, the Phillies’ sixth man has turned out to be one that nobody had expected.
