There was never a question about Humphreys' power potential, but this spring he showed there was more to his game as he developed into a good defender at third. He has a solid arm and good, quick reactions at the hot corner.
"He's developed into his power and last year had a good year driving the ball," D-backs scouting director Ray Montgomery said of Humphreys, who was scouted by Luke Wren. "Gap-to-gap hitter. We like the defense, too."
Humphreys hit .347 with 12 doubles, 18 homers and 57 RBIs this past season.
With the tremendous power potential comes a good amount of strikeouts, but he has a balanced swing and if he can make contact often enough he could be a real find.
Humphreys was recently named Mid-Florida Conference Athlete of the Year.
"He has worked extremely hard these last two years and is very deserving of this recognition," said St. Johns head baseball coach Ross Jones. "He has been a pleasure to coach and has been a leader on and off the field."
