Zach Levine has an article saying that DeShields, Foltynewicz, and Kvasnicka (I have to get a shortcut for those last two) ought to sign quickly.
DeShields indicated he wanted to get started immediately.
"I'm pretty confident that I'll sign with the Astros. Everything worked out how I wanted it to work out."
"I'd be hard-pressed to find a situation where I'd come back. I can't guarantee anything and there's a lot of work to be done. It's a lifelong dream come true."
That's the Bobby Heck M.O.: Take guys who will sign quickly, get them started on their career.
