SATURDAY, 9:57am: According to Mark Gonzales of the Chicago Tribune the White Sox will designate catcher Corky Miller for assignment today. The 33-year-old career backup batted 42 times this year, hitting .205/.262/.282.
8:59pm: SI's Jon Heyman says the White Sox are talking to the Mets about their catchers, probably Castro, and "it appears there's a decent chance a trade can be reached."
4:41pm: According to Adam Rubin of the New York Daily News, the Mets are trying to trade catcher Ramon Castro before Saturday's game (hat tip to MetsBlog). They've spoken to the Mariners, who just lost Kenji Johjima for a couple of months. Rubin says the Mets are not prepared to eat Castro's remaining $1.79MM. Castro is a solid offensive catcher, so he should draw interest.
