Actually, yes. By carrying 13 pitchers and only 5 infielders they need someone who can play every infield position. Halton can't play SS, probably can't play 2B, and given his size would probably be worse defensively than Yuni at 3B. From what I hear Yuni is a really good clubhouse guy - always smiling, always happy, keeps things loose. In a season like this they probably need that in the clubhouse. I have a hard time believing Prince would be worse at SS, 2B or 3B than Yuni. I don't particularly care about the clubhouse at this point. It's a bunch of young guys who are eager to play in the bigs, they don't need Yuni's happy sunshiney-ness.
