They kept it a bit tongue-in-cheek, giving Jones the third-base bag used in Monday's 13-inning marathon, one that was signed by the Nationals.
In addition, Jones also got a picture of former teammates and current Nationals Mark DeRosa and Adam LaRoche.
The Nationals also returned to Jones the bat he used to hit the first home run at Nationals Park. That came in the first game played at Washington's then-new ballpark on March 30, 2008, when Jones hit a solo homer in the fourth inning.
Washington also congratulated Jones with a message and a video.
