Hello and welcome to the 2021 edition of Pebble Reports! Like 2019, Pebble Reports will be published once per week on Mondays with a level-by-level update on standout prospect performances. Daily scores and PuRP highlights will continue to be included in Rockpiles, but weekly individual performances will be highlighted in the Monday Pebble Reports.
Remember that the realignment of the minor leagues means that the Rockies will only have four full-season affiliates — Triple-A Albuquerque Isotopes, Double-A Hartford Yard Goats, High-A Spokane Indians, and Low-A Fresno Grizzlies — plus two Dominican Summer League teams.
