It's also very possible that the unaffiliated prospect ranking services have Graterol rated much higher than MLB teams actually do. Like I said above, while he's got a huge arm, his body type and physique don't lend themselves to prolonged success. For every Bartolo Colon that finds a way to make it work, there are 20 Luis Ortiz types who are ranked highly by independent scouting services and prospect rankings, but simply don't hold a lot of value and end up washing out. I completely agree prospects can be overrated and maybe his size limits him going forward. However he is a much better prospect than Ortiz was. He hits 100 mph with an almost 4 to 1 K to walk ratio. ERA of 2.48 and WHIP of 1.07. And he wont turn 22 until this August. I would have been very happy to get him Well, it appears that Graterol's medicals have potentially put this deal on hold. I'm not fat shaming, and obviously there are all types of body types who can be great baseball players, but when you are considering trading two franchise-type players for a package that includes a 21-year-old kid who is already tipping the scale at near 280 pounds, there are going to be concerns. Perhaps Graterol can be transitioned into a relief role, but unless he does that and is Hader-level good, that would substantially decrease his value.
