It's all over on Saturday afternoon.
That's when MLB's waiver-trade deadline hits, putting an end—only temporarily, of course—to what has been months of banter, speculation and baseless trade rumors.
Between then and now, each of the 15 teams that I still consider to be viable playoff contenders will be looking to shore up their rosters for the stretch run, with some of those contenders already pulling off deals that, in some cases, may have improved their playoff chances slightly.
But finding that short-term success via the waiver wire can be costly.
Just ask Pittsburgh, which in 2008 traded a struggling third baseman named Jose Bautista to the Toronto Blue Jays for a player-to-be-named-later, which wound up being catcher Robinson Diaz.
Bautista has gone on to become one of the premier sluggers in the game, while Diaz appeared in a total of 48 games for the Pirates, last playing in the major leagues in 2009 and currently spending time with Milwaukee's Triple-A team in Nashville.
Think Pittsburgh would like a do-over on that one?
That's the kind of nightmare scenario that doesn't ever stop stinging—and what follows are the nightmare scenarios for every contender that their respective general managers will be looking to avoid over the next five days.
