ESPN’s Jerry Crasnick reports that the contract is for one-year and worth $5.35 million.
Ramos, 28, batted .229 with 15 home runs and 68 RBIs for the Nationals in 2015, and was also a Gold Glove finalist behind the plate. He earned $3.55 million last year, in which he appeared in a career high 128 games.
In six MLB seasons, Ramos has a .258 career batting average with 61 home runs and 241 RBIs.
Washington still has four arbitration-eligible players to sign: pitcher Stephen Strasburg, infielders Anthony Rendon and Danny Espinosa and outfielder Ben Revere, who was just acquired from Toronto via trade.
