RHP // Michael Santos is the second youngest player on the list, but not by much. The 19-year-old Dominican was born just a single day before the Giants' 2013 first-round pick Christian Arroyo. Santos opened eyes in the Arizona League in 2014, starting 12 games and reaching his five-inning pitch limit 11 times. He also finished fourth in the league in ERA and innings pitched. Putting him on the Mella/Ysla track, he should pitch in Augusta in 2015, where he'll feature a low-90s fastball with tail, a changeup, and his plus curveball. That thing is big.
