The Washington Nationals are the 2012 National League East division champions. The Nats won the division tonight even though they lost to the Philadelphia Phillies, 2-0, because the Atlanta Braves lost to the Pittsburgh Pirates, 2-1, making it impossible for them to catch the Nationals in the two games each club has left.

The Braves game ended as the Nats game was in the middle of the ninth inning. The video above shows the crowd reacting to the news.

In case you missed it, here’s last week’s Washington City Paper cover story on how to root for a winning baseball team. The playoffs start Saturday or Sunday—plenty of time to study between then and now.
