ORLANDO, Fla. -- As Bryce Harper enters the final year of his contract with the Nationals, his agent, Scott Boras, said he has not had any conversations with the team this offseason about a possible extension.
Asked whether he expected to do so this winter, Boras said, "That would be up to the Nationals."
"We've got Bryce for one more year, we're not going to get into what we're going to do with him in the future or what we're not going to do -- describe any talks or anything like that," Nationals general manager Mike Rizzo said. "He's our guy and one of the best players in the game, and I'm glad he's on our team this year."

Harper's impending free agency in 2018 has been one of the hottest topics in baseball for a few years, because so rarely does a generational talent such as Harper hit the open market at such a young age. Harper just turned 25 in October.
So Harper is expected to command a contract that will almost certainly be the largest in MLB history, surpassing Giancarlo Stanton's 13-year, $325 million contract with the Marlins, signed in 2014.
That's because, when Harper is healthy, he continues to prove that he is one of the most dynamic players in baseball. In 111 games in 2017, Harper posted a slash line of .319/.413/.595 with 29 home runs and a 157 OPS+. He is already a five-time All-Star and has won the National League Rookie of the Year and Most Valuable Player Awards.
Another player the Nationals could explore extending is third baseman Anthony Rendon, who is also represented by Boras. Rendon will not be a free agent until 2020, but he is second-year arbitration-eligible this offseason.

Boras said he has not had any discussions with the Nationals about Rendon either, although the topic could come up later this offseason when the two sides discuss arbitration.
"We'd love to have him, extensions are two-way streets," Rizzo said. "He's a guy that is dear to us because we drafted and developed him, and he's played well for us."
