The Nationals announced a series of roster moves today. Outfielder Robert Hassell III and infielder José Tena have been optioned to Triple-A Rochester. Outfielder Daylen Lile has been recalled while third baseman Brady House has had his contract selected. Those four moves were reported yesterday. To open a 40-man spot for House, the Nats designated first baseman Juan Yepez for assignment.

More to come.
