The middle of May is when the wheels really start turning around Major League Baseball. It is when the standings begin to soften up a bit and the separation between first and last place in divisions such as the National League East becomes greater than just a few games.
The middle of May is also when one well-timed move can make the difference between heading into June atop the division or going into the month tied for third, three games out. For non-contenders, this is when the future starts to become the focus and teams begin contemplating who they may be able to trade with next season.
Unfortunately, this is also when the futures of MLB front office executives and managers are called into question because a season that began with such promise suddenly turns into one that is quite forgettable. Such is life in the grandest game around.
Either way, each MLB squad has one move it needs to make ASAP as the month of May grinds on. Let's take a look.
