LOS ANGELES -- Like a lot of baseball fans, Zack Greinke was glued to his laptop in the hours leading up to Thursday's trade deadline. Unlike most fans, Greinke has enough insight into the process -- from having been traded twice and from knowing some of the people involved -- that he feels he can separate fact from fiction as rumors swirl.Then again, maybe not."Not really, because there's some stupid stuff that actually does happen," Greinke said.
