Romero should be on this list. I'd have him as the Twins second best SP prospect behind only Gonsalves, but I suppose he's not quite as close to the majors as the others.
The thing that makes it frustrating is that with the way he plays defense and runs the bases, he really only has to be an average hitter right now to be extremely valuable.
It seems that people don't realize how terrible he is defensively because he doesn't make any glaring mistakes like Delmon, Arcia, Sano etc. He doesn't get to balls that an outfielder should and has a noodle arm, not a good combo.
Looks like that Kirilloff kid can really hit. He's even been playing some CF, which is nice to see. I know he won't play there in the bigs but I would assume he has some decent range if they're sticking him out there.
