This is Rooker's first full season in pro ball, he started it in AA. Twin's way with college starting pitchers. Slegers moved up 2 levels a year, Gibson moved up quickly. Logan Darnell moved up quickly. Now if you were to say the Twins have picked many poor college pitchers, that would be fair. If you look and saw how many of their college pitchers blew out arms, that would be a fair observation. That they do not promote pitchers in season is a fallacy. Short season A leagues are primarily filed with players not good enough for full season A. There may be a few players right out of college, but I doubt if there would be much gain in success of the development of the players.
