Didn't people say the same thing about Beachy when he did the exact same thing in September of 2010? Turned out that it wasn't a fluke and that Beachy was the real deal. You can't sit here and say that Hale isn't capable of doing the same thing. I'm not saying one way or the other because I don't know but I'm not going to act like I know definite either way.
Not a very good comparison. Beachy had much better minor league numbers. Basically, your argument is only saying that anyone who has been mediocre to bad their whole career can excel in the majors... okay, but the odds aren't very good.
Hale minor league stats:
25-28, 3.68 ERA, 368 K, 182 BB, 472 innings
Beachy minor league stats:
15-8, 2.58 ERA, 269 K, 71 BB, 254 innings
The quality is not even close... terrible comparison. I can't say he isn't capable of doing the same thing, but I can gaurantee its not likely. How are you going to tell me Hale is going to be a successful MLB pitcher based on TWO starts, a mediocre spring and a mediocre to bad rest of his career? There's optimism and there is blind hope.
The only reason Beachy surprised everyone was because he only started pitching his last year of college. He was far from any kind of surprise the year he came up if you paid attention to the organization and scouts.
