Fantasy Baseball Prospect Watch | Players Off to Strong Starts: Heston Kjerstad, Joey Loperfido, Nathan Martorella, Andrew Morris, Adam Mazur and More

The MLB season is now two weeks in, and now is the one-week mark for the minor league season as well.

With that in mind, let’s look at some of the top performers so far. We’ll focus on Triple-A players mainly with their season a couple weeks in, but also mention some players at lower levels. I’m also going to focus on players age 25 or lower.
