The Los Angeles Angels have dismissed advance scout Justin Prinstein, who had earned the nickname "Baseball Spy," after he was caught filming the Colorado Rockies' coaching staff from the stands. The incident, first reported by The Athletic, raises questions about the boundaries of legitimate scouting versus prohibited surveillance in Major League Baseball, where teams routinely send advance scouts to observe opponents but are barred from certain forms of covert filming.

The filming reportedly took place during the Angels' June series against the Rockies at Coors Field in Denver, where Prinstein was spotted recording the coaching staff rather than simply taking notes in the conventional manner expected of advance scouts. The Angels subsequently terminated his employment over the matter, though further details of the exact nature of the footage or the club's internal review have not been made public.
