Just to put it in perspective, re: Yorman Rodriguez, Jason Parks ranked him as a better prospect than Jesse Winker coming into the 2014 season. And some people were arguing that Winker should have been a Top 100 prospect coming into the season, and Parks thought Yorman was a better prospect than he was. A few Baseball America writers also had Yorman at the tail end of their Top 100 lists. And no, just in case someone doesn't understand what I'm trying to say here, I don't think Yorman Rodriguez is a better prospect than Winker is, I'm just making the point that in the scouting community, he gets a whole lot more respect than he seems to be getting around here.
Yes, he's been around instructors quite a bit more than most guys have been. But still, 21 is 21. You can keep saying "after all these years", if you put him in Dayton right now you would be seeing a really good season from him and people would be stoked if they had a guy with his tools in Dayton and putting up good numbers at his age. But because he's been in the US since he was 16 and pushed aggressively when maybe he shouldn't have been at times, people haven't seen him have big sustained success and think he's not much of a player.
Going back to June 1st of last year, and excluding May of this year because it was very clear he was injured still and not right, he's hit .283/.341/.428 in 602 plate appearances, mostly at the Double-A level. He's walking more and striking out less than he has in the past this season (sans May). His home ballpark isn't suited for how he hits at all (opposite field approach for a right hander in a park where there were all of NINE home runs hit to right field in 2013 by both teams in 70 games).
Maybe I'm just completely nuts, but I think far too many people are sleeping on this kid because it feels like he is far older than he actually is.
