The Nationals reinstated Reyes (undisclosed) from the injured list Friday and released him, Jesse Dougherty of The Washington Post reports.
Reyes hadn't played in a game with Triple-A Rochester since early July, and he'll now attempt to latch on with his third organization of the season. The 28-year-old is slashing just .217/.317/.392 across 167 plate appearances in Triple-A this season, but there's a decent chance he gets a minor-league contract from another team.
