technically true, but the sum total of that raking at every level was 61 AB above A ball. He now has 67 AB in the majors with an 83 OPS+ so that sample is just as determinative, in fact more determinative than his MiLB career so far. Considering that most rookies see their performance drop in the course of their first season as the league learns their weaknesses, I don't see Langford as having a uniquely positive predictor right now. He may meet the challenge, he may not, time will tell. But that doesn't change that TX bringing him up this fast was more stunt than solid justification. But that's fine, sport is in the end entertainment, and stuff like that is entertaining even if it turns out not to have been in the best interest of the player.
The ROY bonus pick setup will probably lead to more of this though.
