2015 MLB Rookie of the Year Stock Watch, End of May Edition

Major League Baseball has been overrun with youth in recent years, and the barrage isn't letting up in 2015. So if you like high drama in your awards races, the Rookie of the Year is the one for you.

And with the first two months of the season just about over, it's time to check where things stand.

We're going to rank the top five Rookie of the Year contenders in the American and National League, respectively. Simple enough, but understand that there are two ground rules at play:

1. Overall production matters most.
2. Since we're also taking the temperature of the candidates, a guy who's been good all year won't necessarily rank ahead of a guy who's red-hot now.

Before we begin, a fair warning: The crop of rookies in the AL is solid, but it isn't nearly as strong as the crop of rookies in the NL. As such, we'll warm up with the Junior Circuit before moving to the Senior Circuit.

Step into the box whenever you're ready.
