Of course he can. Aguilar played 3B and the world didn't come to an end. Thames plays in the OF, Miller plays SS, I can go on and on. Aguilar played 7.1 innings, not sure how that is comparable. It isn’t hard to hide someone in the OF and have them be...good enough. Eric Thames is awful out there though and it only should be done in an absolute emergency for the offense. Jonathan Villar has hit LHP well this year and in 2016, but is that really worth defense that sports a fielding % far below .900? I don’t even know why you’d bring this up. They wouldn’t put him at SS when Arcia was hitting like a pitcher, no way in a million years will he see time at 3B. Your examples aren’t even remotely close to comparable. All they do is prove how much worse Villar is at 3B than what are already considered tragic liabilities at their respective positions. My examples are fine. They didn't put Villar at SS because that's a position where you try not to skimp on defense. And they wanted to give Arcia every chance to get his swing back. Even at that, they've played some marginal guys there this year (Sogard, Miller.) Proving my point even further they are willing to sacrifice some defense in search of a hot bat. You say Thames should only be used as an emergency in the OF, yet he has and will be used out there more often until Cain/Yelich return. It's not an emergency, they have other OFs they could have used but once again the bat plays. I don't think it's crazy, you do, sobeit. Edit: Here's the reason you may see Villar play a few games at 3B: vs LHP: Villar: .886 Shaw: .529 It's also why we may even see Aguilar again at 3B when Cain/Shaw return.
