Keith Law from The Athletic released his rankings of the top farm systems in baseball on Thursday. He had some good things to say about the Pittsburgh Pirates after ranking them as the sixth best farm system.
Law does note that he doesn’t believe that the Pirates have a true superstar in his ranks above the complex league. I’ll note that the wording seems odd, since he mentions at the bottom of the article that the system could look better once Termarr Johnson, Anthony Solometo and Bubba Chandler get to full-season ball, so I think he is including them as the complex league players.
