The Phillies are sending Orion Kerkering to Triple-A Lehigh Valley, according to The Athletic’s Matt Gelb.

Kerkering had nothing today after a poor outing Friday, yet Don Mattingly hung him out to try, letting him throw 36 pitches and give up four runs in the eighth against the Mets. He’s now allowed 12 runs and eight walks over seven innings in his last seven appearances. It really doesn’t seem like the Phillies pen is going to have much in the tank in October, in part because Mattingly’s ineptitude.
