With MLB teams roughly 10 games into the 162-game season, there's no true way of telling which teams will be in the playoffs. Sure, the Dodgers are 9-1 now and the Angels are 4-6, but who knows which one will represent Los Angeles in the playoffs—it could even be both or neither.
For those that have been regarded as contenders this season, however, the trade deadline is going to be important, as it always is. There is likely to be a blockbuster move by that fifth or sixth team in the standings to try to not only get in the playoffs but to become league favorites.
Here is a potential blockbuster deal for each team, limited to those generally accepted as being in contention this season. I'm aware there may be different teams than these listed in contention this year. I'm not taking records into account, though; really, is Baltimore going to be first in July? Certainly not.
