So far this season, Helton and Youk have been pretty much the same players. Helton has been a bit better though (HeltonVORP: 23.5, YoukVORP: 22) and if you add that Youk is younger and cheaper, I'd say that Youk may have a bit of an edge. Sure, Helton is more likely to sustain this sucess, but at this point, there is absolutely no reason to move Youk.
