In terms of position players and relievers the Twins farm system has been a great pipeline of talent. Unfortunately, there has been a distinct lack of starting pitchers being able to establish themselves at the major league level. The only guy since Berrios who has had moderate success has been Dobnak and he an undrafted free agent signed out of an independent league. Way too many former top 100 prospects have flamed out in the last 5 years including Meyer, Stewart, Gonsalves, Jay, and Romero. I'm hoping the next crop of Duran, Balazovic, Enlow, Canterino, Sands, and Chalmers has more success.
