Harris said it helps that the Nationals have added a leader in the clubhouse in Mark DeRosa, and an experienced bench.
"They have the role players on the bench. Those guys are solid doing it -- DeRosa, [Xavier] Nady, [Roger] Bernadina if you need somebody to steal a base. They have a great team. They designed it well. It's going to be exciting to see those guys. I just wish them the best. Hopefully, they will continue to play well."
Harris also credits manager Davey Johnson for the good camaraderie in the Nationals' clubhouse.
"He has been in the game for a long time. He can look at a player and tell if they are in the game or spaced out somewhere," Harris said. "He has an edge over some managers. He and [Reds manager] Dusty Baker are pretty much the same managers. They are both icons. Davey knows what he is doing over there. He just a great guy to talk to, and great guy to be around. Those guys love playing for him. You can see it."
Harris knows the Nationals well. He played for the Nationals from 2008-10 and was considered one of the better bench players they've had in recent years.
