Hat tip to Jayne over at What the Heck, Bobby, who informed us that the Astros have signed minor league catcher Jair Fernandez. Jair has spent time with the Seattle and Minnesota organizations, where he's shown to be a light hitting catcher with an outstanding CS%.
In just over 1500 minor league plate appearances Fernandez has hit .236/.326/.335 and has caught 169 of 421 attempted base stealers, a 40% rate. He'll likely be minor league depth, either in Corpus or OKC.
