The dog days of summer have passed. Soon, Labor Day will too and mark the unofficial end to the sunny season. From there, the race to the Fall Classic kicks into high gear.

As the chances to add talent from outside become less frequent, teams often look to the farm for late-season impact. Last year Joc Pederson, Maikel Franco and Brandon Finnegan were among the top players added. The Royals used Finnegan as a weapon all the way through the World Series.
