I'm still in no rush to call up Hiura. If he's truly changing his approach, give him some time to stabilize himself. He's not a replacement for Voit, he's just not. I consider Voit not part of the conversation. He needs to be replaced, that much is sure, but Hiura doesn't fill his role as a lefty masher. The Brewers need to replace Voit but Hiura doesn't do that, he's just another guy who hits righties. Arnold needs to go find someone who can play a corner role and OPS .800 against LHP.
And in a couple of weeks, I'll be ready to move on from Winker if he doesn't right the ship and Hiura does fill Winker's role if called up.
