In approximately this order:
Carp
Lueke
Seager (when he comes back after 7/31)
Gutierrez/Halman
Right now there are huge holes at LF, 3b and CF. If they can be filled inexpensively with consistent-OBP guys -- and if League can be off-loaded before arb payday [either before 7/31 or over the winter] -- then, the spreadsheet looks a lot more Fielder-friendly.
If you're trying to fill 4-5 spots and sign Prince, I don't see it happening.
Y'all got me amped up on Carp again, the last three times that happened he underwhelmed. Maybe it'll stick this time.
Seager will be back because no way all three of Figgy, AK and Jack W will still be on the roster after 7/31. Maybe all three will be gone. Kyle is 5-for-13, 1 HR in his return to AAA.
