This is still unconfirmed, but supposedly the Giants will call up catching super prospect Buster Posey. Posey is tearing up the PCL with a .349 BA, .442 OBP, and has hit 6 homers. He has been seeing action at 1B in AAA so it seems likely that Molina will still hold primary duties behind the dish (even though Posey is no slouch with the mask on.)
