I forgot to add....These young prospects sure do excite me. I've been following the Yanks' minor league system for a few years now, and am confident in the abilities of many of these guys.
Just look at next year's possible rotation:
Wang
Hughes
Chamberlain
Kennedy
Pettitte
Four of those guys are young and cost controlled. One can also not forget about the other young arms the Yankees have in their system, including Humberto Sanchez, who they received in the Gary Sheffield deal. Humberto had TJ this past year, but is progressing well and should be pitching sometime in the Spring.
