No, but Esteury Ruiz just had one dominant year at 23 in the upper minors and had atrocious batted ball data, culminating in him having by far the lowest average EV in the majors this year. Black's is nowhere near that low. Vargas, interestingly, put the ball in the air a ton with a 47%. FB rate (which you want Black to do), yet had his worst season of his career including the minors. Black has plus speed so I don't think you don't want all of his contact going in the air. Fact of the matter is, unlike Ruiz and Vargas, Black has put up a +.400 OBP everywhere he's been. He may not reach quite that level in the majors, but there's very little reason to think he won't get on base at a well above average rate, which is precisely what you want from your #2 hitter.
As Wiguy points out, you're completely ignoring his AA data where he spent the vast majority of the season and then decide to extrapolate out a much smaller sample size from AAA....
If this were a one-off, I wouldn't think much of it other than I simply disagree, but with some of the other articles you've been pumping out lately and with seemingly increasing frequency, it sure as heck is going to raise eyebrows on a Brewers fan site.
