15. Miguel Sano
"Sano missed all of 2014 with Tommy John surgery but was fully ready to play this winter. He had a very high profile July 2nd signing process, complete with a controversial documentary, accusations of falsifying his age, bone scans and a surprise late entrant scooping up the player. Sano was seen as a once-in-a-generation talent with 80 raw power and the ability to stay in the infield to go with an advanced feel for hitting. That’s all still true, but Sano has added a lot of strength — he’s at least 6-foot-4, 240 lbs. now and likely will get even bigger. As such, most scouts now assume he’ll end up at first base in a few years. He’ll head to Double-A or Triple-A to start 2015 and should get a big league look late in the season if he proves everything is fully back."
