with Matt Harvey set to clear waivers tomorrow, I have the #2 waiver in my keeper league and can keep him for $2 of my 8 player $90 cap if I claim him. The only $2 keepers are rookies claimed after they are added, and given all the prospects Yahoo has put in, they are a rare lot. The only other guy I can think of who isn't in Yahoo and would be worthy is Taijuan Walker, but no guarantee he comes up this year (in fact I would bet he doesn't at all).
Jake Odorizzi, Mike Olt, and Carlos Martinez are the other guys I can think of.
This isn't as much of a DTKW question as much of a "...who else is there, who are you holding out for?"
