2018 Triple-A Postseason Rosters - PCL, IL Series

The following umpires were selected to officiate MiLB's 2018 Pacific Coast and International League postseason series. Semifinals information from MiLB; Championship (PCL, IL and Triple-A) information from Ump-Attire.

As we learned from Brian Hertzog in Episode 3 of The Plate Meeting, MLB fill-in umpires will tend not to officite the MiLB postseason so as to retain availability for the major league level throughout the month of September.
