Zach Levine's Minor League Notebook has some info in it, notably regarding Austin Wates:
Wates credited some of his success with the bat to the fact that he remained at Virginia Tech as the two months went by from the draft until his signing. He kept up his work in the university's strength training program and kept hitting.
"I feel like I could be a really good center fielder some day, but I'm going to do whatever they have me do."
Wates will head to the Instructional League this fall.
