Derek Jeter is saddened by the thought of not having longtime teammate Bernie Williams on the club. "It's unfortunate," Jeter said yesterday after a baseball clinic for kids at Legends Field, the Yanks' spring-training home. "You never like to see that aspect. You know what Bernie has meant to the organization. "I would love to see Bernie come back. It's a decision he has to make. Hopefully, he makes the best decision for him."
