With playing time he'd be worth a spot in a 12 team league. I brought him up from the minors in one of my 16 team dynasty leagues this week and he's outproduced most everyone else on my team -- he's had a really great week.
He and Quentin have been the only hitters for CWS (Dye has been good too I guess) so it would be stupid to sit him for Uribe. Supposedly the plan is to put Uribe in, but that would probably be a bit of a death sentence...replacing a hot hitter with Mr. 0.220 Uribe would be illogical.
Anyway, yeah he has value. Stash him.
