He's the highest pick, other than McGeary, who hasn't signed.
I found this at BaseballAmerica,com about him:
He's 21 so he's not just coming out of high school.
Maybe he isn't planning on playing pro baseball is the only reason I can think why an 18th rounder with those "strengths" wouldn't have signed already.
...and why did his parents name him Swain Sawyer Carroll??? 
LOL. I don't know, but the name sure is something we could all have some fun with.
