So right now we have:
Osuna
Grilli
Biagini
Loup (only lefty, so close to lock, but does have options)
out of options
Bolsinger
Oberholtzer
Schultz
remaining options
Campos
Leone
Barnes
Dermody
Girodo
Of the out of options guys, Bo Schultz is probably finished here. Bolsinger is probably close to a lock to make the team, as he's a very useful swingman and probably wouldn't make it through waivers. So there will probably be some competition between Sparkman and Oberholtzer for one spot, with Sparkman having more upside, and thus the inside track. So something like:
Osuna
Grilli
Biagini
free agent signing
Loup
Bolsinger
Sparkman/Oberholtzer/one of the guys with options only if they other two suck in spring
