Quite a bit has changed since the 2013 MiLB season began in April, and folks have been clamoring for a mid-season prospect list. Well, here it is, 50-deep. But before we get into it, a quick primer on the criteria for this top 50: There was no specific timetable considered, so the rankings below can be considered a dynasty league list. You’ll notice that the ETA’s here range from this season all the way to 2016. To prevent any overlap with lists that Grey and JayWrong put together last week, I’ve included only prospects who are currently in the minor leagues. That means I had to remove Christian Yelich and Jake Marisnick from the board after news of their call-ups — Yelich was #7, Marisnick #40. It also means I couldn’t list Carlos Martinez, who’s currently working in relief for the Cardinals — he would’ve been ranked right around #20.

Anyway, I’ll be writing notes on all of these fellas during the off-season, once the dust has settled on the 2013 season and I’ve had a chance to take a more thorough look at depth charts, injuries, etc. For now, I’ve included only a few pertinent details: age, current level, fantasy impact categories, and ETA. Each player is linked to his player card on Baseball-Reference.com, or his Razzball player card where possible. My hope is that this list will help dynasty leaguers sort out their rosters as keeper deadlines approach. Enjoy.
