MLB.com is stating that it would probably be a Padre prospect for Scott. They speculate that the Padres may make available catcher Nick Hundley, outfielder Will Venable or pitchers Josh Geer or Wade LeBlanc.
Geer is a Rice guy, so I'm sure Drayton has put Wade on notice. Not a bad thing (actually) as he went 16-6, 3.20, 102 K's, and 27 BB in 171 IP.
