Yuni's had some big hits and a couple game winning HR's, so if you haven't checked the numbers in a while, you might think he's carrying his weight and that his continued presence in the line-up is a defensible managerial decision. He's not, and it's not.
Yuni's line stands at .248/.283/.423. That's good for a .299 wOBA and an 85 wRC+, 15% below the MLB average. If he were playing great defense at C or SS, you could stomach that offensive line, but instead, he's playing statue at 2B every day.
I'll give him that he has good dexterity and he looks fine turning the double play, but he's fat and slow, and he has no range in either direction. Yuni seems to give up hits on balls that should have been outs almost every game.
Please Ned Yost. Fight your primal urges, and remove this package of awful defense and a .283 OBP from our line-up. We'd like to win more, and Yuni is costing this team wins.
