Lo Duca, waived by the Nationals after their ninth straight loss on July 31, will report to Triple-A Albuquerque.
Lo Duca, who signed a $5 million, one-year contract with the Nationals as a free agent last December, batted .230 with 12 RBIs in 46 games. He missed 52 games this season with two injuries to his right hand - a bruise and a broken hand. Along the way, the 36-year-old Lo Duca lost his starting job to Jesus Flores.
Lo Duca, a career .286 hitter, apologized to Washington's fans after being let go.
