Sports agent Scott Boras addressed reporters as the general managers’ meetings wound down Wednesday afternoon, commanding the media masses into a massive scrum around him, then navigating questions for 45 minutes or so, in keeping with meetings tradition. Questions fly in from all around, about topics far and wide. One of them almost always involves Bryce Harper. Wednesday, roughly a year from when Harper is scheduled to become a free agent, that question was whether Boras has spoken to the Nationals about a contract extension that could prevent Harper from becoming a free agent at all. “No,” said Boras, who then indicated that future discussions of the topic will be “up to the Nationals.” The Nationals, for their part, will be open to talking about an extension, according to a person familiar with the situation. Of course they will be. Harper is one of the best players in the game, one of its most marketable stars, a transcendent talent. The Nationals drafted him and helped develop him. They will try to keep him, if they can. But as of now, according to Boras, the sides have not talked about a deal.
