Vidro made the NL All-Star team in both 2002 and 2003, hitting over .300 both seasons and winning the Silver Slugger as the best hitting 2nd baseman in the NL in 2003. Vidro played 3 more seasons with the franchise, including the first two seasons when the Expos moved and became the Washington Nationals. Due to injuries to his right knee, ankle, and quadriceps muscle, Vidro played in only 87 games for the Washington Nationals in 2005, 8 of which were as a pinch hitter.
