The first round pick of the Houston Astros (21st overall) in 2009, Jiovanni James Mier was universally acclaimed as the best 'pure' shortstop in the draft class. A superior defender with good range, soft hands and a strong arm, he seems very likely to stick at the position. JJ's bat isn't quite as beyond question just yet, and he hasn't done much to improve that with disappointing A-level outings in 2010 and 2011, but he should have a couple of years of additional rope to work with before Houston moves on. Don't forget about him.
