Washington Nationals third baseman Ryan Zimmerman, who previously won a Gold Glove at the position, may eventually have to change positions because of throwing issues.
Zimmerman made four throwing errors over a five-game span, and said it had nothing to do with his offseason shoulder surgery.
Adam LaRoche is currently Washington's first baseman.
"I'm not sure it's the yips because he can make the throw on the run," said a team official. "It's when he sets up that he has the problems. It's something we don't want to bring attention to because it makes it worse. Not sure there's much we can do."
