Consider me among the buyers on the Brewers' Jean Segura. I know he didn't hit many home runs in the minors, but if I may quote the Baseball America Prospect Handbook from 2012, the last year he was eligible:
"His bat is lightning-quick, and he could consistently bat .290 with as many as 20 homers at his peak."
Granted, age 23 isn't considered a player's peak, but given Segura's contact rate, as long as he's capable of putting a charge in the ball, he's a good bet for double-digit homers. As of now, I'll predict 15 for him.
The stolen bases and batting average are almost assured at this point, so 15 are enough to make him a high-end shortstop. Right now, I rank him 10th at the position, but I've been toying with moving him ahead of Asdrubal Cabrera and Elvis Andrus for a few days now.
