The Diamondbacks used the 70th selection in the draft on SS/2B Isan Diaz a high school player out of Springfield Massachusetts. This was the second position player taken by the Dbacks after selecting two pitchers.
Here is what perfectgame.org had to say about Diaz:
"“Isan Diaz is a 2014 SS/2B with a 6-0 180 lb. frame from Springfield, MA who attends Springfield Central HS. Solid athletic build, good present strength, looks stronger than last observed. Left handed hitter, big pull back load, flows into contact, timing can be impacted but approach develops big bat speed, explosive hands at contact, loose and fluid swing with lift and extension out front, has pull side power, owned mid-level pitching in every at bat and made hit look easy, advanced hitter with tools and feel. 7.22 runner, middle infield actions, stays balanced and works through the ball, plays under control and lows the game down, compact quick release, second base profile and tools. Can be a high level offensive second baseman. Signed with Vanderbilt.”"
This is somewhat of a surprising pick at this stage of the draft especially if he pans out as a shortstop given the team’s depth at that position. He could also turn into a 2B. However, he has already committed to Vanderbilt, the third of four Dbacks picks to go that route. This guy has a lot of upside, and plenty of talent, we’ll see how he pans out down the road.
