Palmisano was the rule 5 catcher we got from the Brewers, who didn't want him back when he didn't make our club out of ST. He was on the Hooks roster and prior to getting his release was on their 7-day DL. The other two catchers on the Hooks roster right now are Brian Esposito (30) and Jonathan Fixler (22). The two catchers at Round Rock are Santangelo and Towles. I would assume a Castro sighting in Corpus this summer is extremely likely, as neither Esposito or Fixler appear to be prospects.

Estrada was once a highly regarded, back end of the bullpen prospect, but was hurt most of last year and has generally fallen off over the last three years. Giving up on him might pave the way a little bit for younger, more valued prospects to get bumped up a notch.
