The Washington Nationals and first baseman Adam LaRoche have continued discussions on a new contract for next season and beyond, via Adam Kilgore of the Washington Post.

LaRoche, who originally signed a two-year, $16 million deal with an option for a third season, could pick up his end of the mutual option. The Nationals would have no objections to that, but the soon to be 33-year-old is seeking security in terms of a multi-year deal after having one of his best campaigns in nine years.

The Nationals have five days after the completion of the World Series to strike a deal with LaRoche, or he will officially become a free agent and be able to sign with any other team.

LaRoche batted .271/.343/.510 with 33 home runs in 647 plate appearances for Washington last season. The 33 home runs were a new career high for LaRoche while his 100 runs batted in tied a career high.
