I don't think anyone really has any idea what he can do defensively right now. He was the DH all year, including for Team USA to protect his arm in his draft year. His arm is apparently healed and he's a good athlete. Honestly though, my guess is if the Brewers are playing him at SS or 3rd base in the near future, things aren't going that well for him and they're trying to improve his value by seeing if he can handle those positions. If his arm is healthy...and it sounds like it is, and if he's as good of a hitter as the scouts all said, he should sail through the system. Playing him anywhere other than 2nd/LF would only slow down that progress. As to whether he could...again, nobody has seen him throw and really knows. A lot of people have opinions, but most of those are based on other opinions of people who haven't watched him play defensively in a while...and probably didn't even watch him play much then as he wasn't much of a prospect coming out of HS. So flat out dismissing the idea is just guessing(as I am). But really, the best question would be why? If he can be a elite hitter for the Brewers at 2nd base....all the better. No reason to make a blue chip prospect move. It's about adding options. If Hiura can play 3B, that means you can replace Shaw (directly) or Thames (indirectly). If Hiura moves up as fast as folks here expect, why not? If Hiura plays some shortstop, then the Crew has insurance in the case that Arcia's hot streak is just a flash, and he reverts to the sub-.700 OPS hitter he was before June. If Hiura is as good a hitter as people here think he is, I bet he could be plugged in just about anywhere on the field. I think too big a deal is being made about defense sometimes. If Hiura posts Wade Boggs-like numbers, stick him at third, short, or even right. Just get his bat in the lineup.
