Needing a roster spot for the return of Gio Gonzalez on Wednesday, the Nationals optioned lefty reliever Xavier Cedeno to Triple-A Syracuse late Tuesday night.

Cedeno, 27, made just one appearance in his recent stint with the big league club, a scoreless inning against the St. Louis Cardinals on June 14. He was called up the day before when starter Blake Treinen was sent to the Chiefs.

Gonzalez will likely be the corresponding move, though it has not been announced. He is expected to return from the disabled list to make his first start since May 17 when he went down with left shoulder inflammation.
