Jenkins - Low 90s FB. Hard mid-80s slider. Developing a change. I'm not enamored with him there. More a back of the 1st rd guy
Myers - Catcher who may grow out of the position but can/has played 3B/SS as well as pitched. If he moves off of catcher, I'd imagine it would be 3B. Good solid bat with power. While some might call him a reach at #10, he isn't too far below that IMO (maybe #15ish)
Trout - NJ player so Dana Brown would be happy ... CF is a questionable position for him moving forward but like Myers (as a CA) not a foregone conclusion he can't do it. Solid bat. Good speed. Probably in the mid-20s pick wise IMO
If those are the three, I'd prefer Myers
