Welcome to our first installment of ranking the best fantasy prospects for 2013. Each week, we'll update our Top 10 to clue you in on which minor leaguers can help your fantasy team win this year.
Note that the rankings and information differ from my normal work for Baseball America. In this space, I'm not as concerned with a player's all-around ability or long-term impact; only his ability to put up fantasy numbers in 2013 matters. For instance, Astros shortstop Carlos Correa and Twins outfielder Byron Buxton were the top two picks in the 2012 draft and they're loaded with tools, but they're not close to being ready for the majors, so you likely won't see their names in the rankings this year.
To be honest, at the outset of spring training, I wouldn't have put Red Sox outfielder Jackie Bradley Jr., Marlins righthander Jose Fernandez, Twins outfielder Aaron Hicks or Mariners right-hander Brandon Maurer in the Top 10. Even a week before Opening Day, I wouldn't have ranked Fernandez. But they all broke camp on big league rosters, a testament to the uncertainty of prospect ETAs.
