Herz is not a fringe prospect. Getting that back for Rosario or Winker would be huge. That alone is worth keeping them in the lineup
agreed. Made is probably better than a fringe prospect, too.
I don't think either Rosario or Winker will play their way to being Candelario at the deadline. No one should expect that kind of return. But, between the two, I think you could get a return.
That said, a Rosario / Robles in one OF slot, a Winker / Senzel platoon at DH (until / unless Lip is sent down and Senzel is at 3rd), with Thomas eventually working into the mix, to go with Wood and Young as primary starters in CF and RF (again, leaving room to play Thomas more than a strict platoon), kind of works. If it squeezes Gallo or Meneses's time, so be it if they can't keep up with Rosario, Winker, Senzel, and Thomas.
