If Alex Rodriguez could handpick the team he plays for, Boston might well be No. 1 on his list. According to a source who has talked to Rodriguez recently, he'd love to play for the Sox because he thinks they can win multiple championships. Meanwhile, agent Scott Boras has been pleasantly surprised with the early interest in Rodriguez. "Several teams have expressed an interest and there have been a couple of surprise teams I never expected to hear from," he said. Boras would not reveal any names (one of the surprise teams is thought to be the Marlins). Asked whether A-Rod would be OK shifting to shortstop, Boras said, "I haven't really discussed that with Alex yet. I will if there's a need to." Whither the Yankees? "That's something I will keep between Brian Cashman and myself," Boras said. "I'm not making any more comments about the Yankees."
