According to Nick Cafardo, Sox special assistant Allan Baird has been watching Jarrod Saltalamacchia in the Dominican:
First priority remains a catcher. They have been in a wait-and-see mode with this, but the Teixeira signing might escalate things. Will offense be more of a priority in a catcher now? If so, Miguel Montero of Arizona might be more of a target, or Jarrod Saltalamacchia, who played winter ball in the Dominican for a few weeks but has returned home.
According to major league sources, Sox special assistant Allard Baird unfortunately watched Saltalamacchia on his worst defensive night in winter ball, though other scouts who watched him regularly thought he was fine behind the plate. He's certainly a player with the potential to hit for power.
Finally, focus has shifted. I think this is a good step after what happened yesterday. Saltalamacchia has been killing the Dominican Winter League as of late, but of course I can't find any recent stats to back that up.
