What happened: Philadelphia's improvement since the trade deadline has come largely from internal changes, while Luis Arraez and Brooks Raley have supplied limited immediate impact. Aaron Nola and Andrew Painter have stabilized the back of the rotation.

Why it matters: Bryson Stott and Alec Bohm have settled into new defensive roles, strengthening the infield. Bryce Harper and Justin Crawford have also provided steadier offense.

What to watch: Painter's new changeup and Nola's recent run prevention will test whether the rotation gains can hold.
