Rank
10 Javier Baez CHC AA
51 Corey Seager LAD A+
8 Carlos Correa HOU A
6 Xander Bogaerts BOS AAA
20 Addison Russell OAK A+
90 Brad Miller SEA MLB
88 Chris Owings ARI AAA
5 Francisco Lindor CLE AA
This list is sorted by their 2013 OPS (all between .840 and .900 except Lindor at .787). Quite impressive crop of SS on the way or in Miller's case already playing. Miller's OB% skills are something to marvel at.
Wonder if 3 or so of these guys turn out like the Mid 90's Arod, Jeter, Nomar, Tejada crop.
