Eno Sarris of FanGraphs/Fox reports that the MLBPA will be tightening up the rules which must be followed in order to be certified as a player agent:
We hear about Scott Boras and guys at his level all the time, but rarely do we hear about the host of agents who only have a couple of clients and operate below the radar. Anecdotally you hear about some bad practices among these folks. Sometimes unethical but more often just some straightforward malpractice when it comes to the day-to-day management of their clients’ affairs. Presumably the new rules are aimed at that.
Of course, oftentimes, such professional certification measures are also aimed at reducing the number of new people entering a given field too.
