I just heard a Cashman's interview on ESPN 1050 Radio. When you heard Cashman said, "We will all know what Sexson's decision is one way or the other.", it seems to me this is Cashman way to tell us: Yankees already reached some kind of agreement with Richie Sexson.
Of course, Sexson is not big time player, but you never know. It's good to have as many as helps we can get.
