I don't think half of these teams know what they are doing yet so it's pure speculation on my part but...
Yankees- re-sign Soriano or Rivera? - Rivera will be the closer until he retires.
Blue Jays- is Janssen the guy or does Santos come back - I'd say Janssen has the job. Santos will have to earn the roll.
Tigers- re-sign Valverde or roll with Benoit or Coke? - I'm guessing they will be busy this offseason finding someone else.
KC- Is Holland the guy? - For now. I think spring training will have a competition for someone to earn it, but for now he has the leg up
Twins- ? - no idea
A's- is it Cook or Balfour or someone else? - Probably much like this year, many people will get chances.
Marlins- Cishek has the role all to himself now right? - With a new manager coming in who knows, but I think they like him in a setup role, ultimately
Mets- Is Frank Francisco the guy still? God I hope not.
Nats- do they stick with Clippard or go back to Storen? Storen.
Cubs- stickign with Marmol until they trade him right? Yep.
Giants- Brian Wilson gets it back next year right? If healthy yes, if not, Romo is a damn good clone.
