I think that rather than thinking about players first, start with roles first. I come up with catcher, left-handed bat, infielder, outfielder.
catcher: Seby
left-handed bat: Sheets
outfielder: Leury, Marisnick, Billy, Hasely
infielder: Leury, Alberto, Romy
Burger is the worst fit. I'd DFA Leury and then decide Billy/Marisnick, Alberto/Romy. I'd pick Marisnick as he has a better chance of occasionally running into a pitch and Alberto as they can still hid Romy in AAA.
