Gio Gonzalez (shoulder) allowed one run on two hits and four walks over four innings in his final rehab start with High-A Potomac on Thursday. Gonzalez needed 79 pitches to cover the four innings, but he did record seven strikeouts. Although he's thrown a total of just 7 2/3 innings in his two rehab outings, Gonzalez has gotten his pitch count up enough that he should be fine to return to the Nationals' rotation next week.
