DENVER -- Nationals reliever David Carpenter, who hasn't pitched since July 5, started a rehab assignment on Wednesday with one inning at Class A Advanced Potomac.
Carpenter threw 15 pitches and faced five batters, yielding one run and one hit with a walk. While some relievers' rehab appearances are often fairly short, Nationals manager Matt Williams said Carpenter's return may take a little longer.
"He's been off for a little while," Williams said on Wednesday. "So the schedule is such that he pitches, gets a day [off], pitches, gets a day [off], pitch, gets back-to-back [days off] and then is ready to go.
