Nationals manager Matt Williams announced Sunday that Gio Gonzalez (shoulder) will return to the Nationals starting rotation on Wednesday against the Astros. Tanner Roark will get the ball in the series opener on Tuesday. Gonzalez has been sidelined since May 18 due to inflammation in his pitching shoulder, but looked good during his minor league rehab assignment. With the plus matchup, it's probably a good gamble to re-insert Gonzalez into fantasy lineups immediately for the coming week.
