Update: For more details, check out Seamus' liveblog.

A-Rod's press conference will be held today at 1:30 PM ET. In addition to Jorge Posada, Andy Pettitte, Mariano Rivera and Derek Jeter, CC Sabathia, Mark Teixeira, A.J. Burnett, Joe Girardi and some of the coaches will also be attending.

MLB.com will have live coverage starting at 1 PM. It's unclear if it'll be video or audio, as they just have radio page right now. So, it may just be audio.

Edit: It'll be on ESPNEWS and YES, as well, as Seamus noted.
