Burly really doesn't play RF well at all. He's 1B, DH, LF at best. Therefore tradeable. Since he's showing the best bat of the bunch, get something decent.
Walker is also still bad in RF. He has to still hit his way onto the team. Showing better at bats lately. But ought play everyday finishing out then take advantage of the opportunity. But also trade bait because he still has young prospect sheen. His exit velocities are what give you pause in dumping him.
Ditto for Gorman. He has to hit his way on the team finishing out. Defense at 3B has to be adequate.
Scott is good CF. Very so-so bat. Can he or the Cardinals do better? Does Church offer an alternative?
Winn is the only one I would definitely keep. Approaching GG defense at short, cannon arm. Covering for whatever deficiency Gorman or Saggese offer at 3B. The bat just looks better since the AS break. I have not looked at stats.
Trades should be for SP prospect first. Then add a bat. But Bloom may just punt and continue the "development runway season" into next year.
