Oh boy. There are a lot of people on the list here, but that isn't because the Astros are deep with 3B talent. There aren't any top-shelf prospects here - so we're going to think outside the box and include a number of possibilities.
Jimmy Paredes (22) - he has played 2B until recently. His offensive numbers (9HR, 26 SB, .755 OPS) show some spark (though note the 15/72 BB/K ratio), but the main question might be whether he can stick at 3B.
Jonathan Meyer (20) - he has a good defensive reputation (12 errors), but his stats at Lancaster aren't too impressive in an offensive environment (9 HR, 1 SB, .688 OPS).
Mike Kvasnicka (22) - his Lexington totals this year are solid but unspectacular: 3 HR, 1 SB, .722 OPS, 22 errors. Could his 19 doubles be a sign that he could develop power?
Matt Duffy (22) - at Tri City, the 2011 draft pick has shown doubles power (7 doubles) to accumulate a .756 OPS. 0 HR and 0 SB, with 9 errors.
Jean Batista (19) - he plays mostly at 2B, but he has played a handful of games at 3B, and he would have time to adjust to that position if the Astros went in that direction with him. For the GCL Astros, Batista has 1 HR, 2 SB, a .751 OPS, and 9 errors.
In the "other" category, we have David Flores (24), Erik Castro (23), Tyler Burnett (22) and Darwin Rivera (19). The first three of these guys are getting more time at 1B or DH. But with this field, they should probably still be considered.
The 1B voting has closed. It was close. Nash beat Hinze 44 to 42. Altuve is still winning in a landslide at 2B. Villar leads Mier 39 - 19 at SS.
It will be interesting to see who wins out at 3B. Voting is open until Tuesday evening, 10 PM, central time. Vote after the jump.
