It’s nerve-wracking and exciting when a prospect is called up to the big league club. A team devotes countless hours of development into these players, so it’s always nice to see them pan out. These are the top performing MLB prospects thus far in 2016.

There’s been a recent youth movement in MLB and we’re seeing stars emerge at younger ages. In the recent months we’ve seen a couple of players get their chance to shine on the 25-man rosters.

It’s becoming a fascination among fans to scout and closely watch minor league players and teams’ prospects in hopes that they will one day become the face of the franchise. Between top prospects lists and minor league notes, there are a ton of ways to familiarize yourself with rising players.

Whether it’s in the bullpen, on the field or in the starting rotation, there have been a number of promoted prospects making themselves fit right in on the major league level. These are guys who were once considered the top or one of the top prospects in their franchise’s farm system. A lot of these guys will be considered for Rookie of the Year in their respective leagues.

In order to be considered as a rookie, a player must not have exceeded 130 at-bats or pitched at least 50 innings in previous seasons. The only other option is to have accumulated 45 days or more on the 25-man roster. Some of the players that’ll be listed here will also be considered for Rookie of the Year, while others who haven’t fulfilled the requirements won’t, but still could qualify before the season ends.

Based on statistics and impact on the team, we’ll rank the top prospects who have performed this season. The only players who will qualify for this list one are prospects who were ranked 10th or better in their organization after 2015.
