After the Nats were swept in Miami at the hands of the Marlins, they have won eight of their last ten and the last five in a row.
Harper got the Nationals on the board in their latest victory over the Toronto Blue Jays with a mammoth blast in the third inning to give the Nats a 1-0 lead. They never looked back and won the game 4-2.
Many though that the Nats would have issues going against American League teams on the road, but they have proved that that is not an issue. They are coming off a sweep of the Boston Red Sox at Fenway Park and are on the verge of sweeping the Blue Jays in Toronto.
The Nats biggest challenge might come when the red-hot New York Yankees make their way into Nationals Park this weekend.
The Nationals are quickly becoming one of the best teams in the league and their dominance over the American League helps the Nats in the argument of who the best team in the MLB is.
The pure brilliance of Stephen Strasburg and Gio Gonzalez give the Nats two Cy Young candidates in the front end of their rotation. It is hard to find a starting five that can contend with the Nationals' five.
Their lineup continues to surprise, even with Michael Morse still getting back in the swing of things since returning from his season-long DL stint.
The one person in the lineup who has been a sure thing has been Harper and he is crucial to the success of this team. He is hitting .307 with seven home runs this season and provided the spark that this team needed.
It might be too early to tell, but thus far the Nats are passing every test in their pursuit to show the rest of the baseball world that they are the best team in the league.
