If the Washington Nationals want to keep Bryce Harper long-term, they'll have to initiate contract extension talks, says agent Scott Boras.

"I think those are club dynamics," Boras said. "Whenever any team approaches me about any player, obviously we have dialogue with them. But at this point in time, Bryce is going to be there for three more years, very happy there. So we'll just go forward."

Harper isn't eligible for free agency until after the 2018 season.

There has been no indication from either side that actual talks have occurred yet and Mike Rizzo has suggested that an extension isn't high on Washington's list this offseason.

"We've got quite a bit of control left on him," Rizzo said. "He's going to be a unique and special situation for the franchise. I'm sure that'll be a discussion with myself and ownership in the future."
