D.J. Peterson

Few prospects have seen their stock crater like Peterson the last calendar year. Entering 2015 the case could have been made that he was one of the top corner infield prospects in baseball. After all, he clubbed 31 homers while hitting .297 across stops at High-A and Double-A in 2014. It is hard to say exactly what happened in 2015 (Peterson said he was trying to do too much), but he managed just seven homers while hitting .223 in 97 games between Double-A and Triple-A before a strained Achilles' tendon ended his season. A well below-average athlete, Peterson was never going to be a big league third baseman, but there were plenty who thought he could hit enough to play first base following his impressive 2014 campaign. Now? Not so much. The rule about first base prospects is they have to hit a ton. When they stop hitting, dynasty league owners stop caring, and, for now, Peterson has stopped hitting.
