According to mlbtraderumors, the following players on the Sox 40-man are out of options:
Four are pitchers, only one position player.
Miller and Mortensen will have to perform consistently well to avoid waivers. One lousy month, or 4-5 consecutive lousy appearances, and either of them will be put on waivers. I can't see Morales or Duberont put on waivers before August, and then only if they really stink it up all year. Duberont in particular, is more likely to get a DL trip with a phony strain than be put on waivers.
Ciriaco is the interesting case. First, I'm surprised he's out of options. WHere was he before 2012? I thought he pretty much came up in 2012 and stayed up. When were his options used up? (How many options does a player have to begin with anyhow?)
Ciriaco won't be placed on waivers unless the Sox trade for an upgrade. So even if he's futzing around at .233 BA or whatever, we're stuck with him. I suppose of Boegarts gets promoted to AAA and is tearing it up for 2-3 months, we might see him brought up for the end of the season and Ciricaco let go; but in September with the expanded roster, that would be unnecesary, since they both could stay. So Ciriaco stays unless the Sox trade for an upgrade.
