Gorzelanny felt elbow soreness before landing on the 15-day disabled list and allowed four runs in four innings on Monday in his first rehab outing.
"It went well and I felt strong out there," Gorzelanny said. "I definitely needed it to get my legs back under me. All in all, I felt really good out there."
Manager Jim Riggleman said he would talk with general manager Mike Rizzo, pitching coach Steve McCatty, team physician Lee Kuntz and members of the Syracuse staff before determining whether Gorzelanny will make another rehab start or return to the Washington rotation.
"He may jump in this next one, he may make another rehab start," Riggleman said. "Tom's going to be a big part of this rotation, whether it's five days from now or the next one."
