The Hot Stove season is upon us, and thus far, we have seen promising signs of moving past the free-agent freeze of the past two winters in the multiple early signings of major free agents by the Braves and White Sox, two teams not known for spending big. Even so, with competitive imbalance at an expansion-era high -- at least in terms of the standard deviation of team winning percentage, a fancy way of saying the spread between the good teams and bad -- it's not hard to imagine who will be competing for playoff spots in 2020.
What one move would turn near-miss MLB contenders into 2020 playoff teams?
