Bryce Harper may have rejected a 10-year, $300 million deal from the Washington Nationals on the final day of the regular season, but that doesn't necessarily mean his tenure with the club is over.

Mike Rizzo says the Nationals are open to more negotiations with Harper in the future, and Scott Boras feels the same.

"I think Bryce is open to a lot of opportunities," Boras said. "He's listened to a lot of things. … As we go through this, I think he's going to hear everything from everyone and he'll certainly make an informed decision as to what's most important to him."

Harper is believed to be seeking a contract worth $400 million.
