Decision day has arrived for Jason Giambi. The Yankees designated hitter must let Bud Selig know this morning whether he'll cooperate with George Mitchell's steroid investigation or risk a suspension. Talks continued yesterday between lawyers for Major League Baseball, the Players Association and Giambi's representatives. The sides were trying to reach a deal for Giambi to speak but limit the scope of the questions he would be asked. These discussions have been going on for two weeks since Selig delivered an ultimatum to Giambi to either talk to Mitchell or face disciplinary action.
