1. Likely out of the bullpen, although if Holland and especially Oswalt keep pitching BP, he could get back into the rotation.
2. It's been said Happ is out of the bullpen for now and will eventually go into the rotation, but I wouldn't trot him out against the AL league, and especially not in the AL East.
3. Set up guy, most likely. Pass.
4. Myers will probably be brought up when the Royals trade some of their OF, so I would guess before the deadline. At the latest, he will probably be called up in September. Worth a flyer I guess, but I wouldn't drop a productive player for him right now.
Bonus: Casilla still technically has the job, but he could get shifted out if he keeps coughing up runs. Broxton is being put out there for trades too, so he might not be closing for much longer either.
