Right, within a year or two is probably not realistic, but the point I was going for is that with a guy like Zunino, he should be advanced enough where he could make an impact relatively quickly. With the Twins, we're used to having all of our draft picks be in the minors for at least 4-5 years before even sniffing the majors. But unless I'm forgetting someone, all of the hitters they've chosen in the first round recently have been out of high school so as 18 year olds, unless they are some kind of supreme talent like Bryce Harper, it's natural to expect that they'd be in the minors for at least 4-5 years. The Twins haven't had a pick this high since Mauer. I don't think it's completely crazy to think that if they took Zunino, who has been compared to Buster Posey as far as his hitting skills, that he would move through the system alot faster than other Twins prospects (assuming he was playing well obviously).
And as far as drafting college hitters in the first round, I just remembered Levi Michael from last year. But he obviously isn't even in the same conversation talent-wise of someone like Zunino.
