Cubs Call Up No. 19 Prospect BJ Murray Jr. for His MLB Debut vs. Brewers
Chicago has called up prospect BJ Murray Jr. for his major-league debut against the Brewers, per MLB.com's Jordan Bastian.

BJ Murray Jr., the Cubs' No. 19 prospect, is heading to the big leagues for his MLB debut against the Brewers, the club announced per MLB.com's Jordan Bastian.
The callup lands Murray Jr. on a roster that has been in motion lately. Matt Shaw was activated off the injured list earlier this week, and the organization worked through the Hoby Milner situation — the left-hander was placed on waivers after his rehab window neared its 30-day limit. Murray Jr. steps into that reshuffled picture.
What we don't know yet
The announcement does not specify Murray Jr.'s role, where he slots in the lineup, or how long he remains with the club. Those details are worth watching as the series unfolds.
The backdrop is a Cubs team riding a remarkable stretch from Pete Crow-Armstrong, who has been putting together a historic August. Murray Jr. arrives at an interesting moment for the organization — though what he does with it remains entirely unwritten.
