In the case of the Nationals, they decided not to offer infielder Aaron Boone and left-hander Odalis Perez arbitration because they are not considered Type A or B free agents.
However, the Nationals have interest in having both players back for next year, but they are going to see how the free-agent market plays out before making any moves on the players.
Perez pitched in 30 games this past season and went 7-12 with a 4.34 ERA, while Boone hit .241 with six home runs and 28 RBIs off the bench.
