I am not so sure. The reason he moved him off the dirt in the first place was to keep him out of Barbaro's shadow. If Barbaro had remained healthy he would have probably gone onto the Haskell/Jim Dandy, then the Travers... Showing Up would have gone up against him time and again, switching him to the turf allowed both horses a chance to shine.
He's got a bit of work to do before he get's the BC, but even if he DID end up racing in the Classic and winning, I have to wonder if Barbaro would get the nod due to the fact that he defeated Showing Up in the Derby....
