Putting in Scherzer was a good decision even if it didn't work out.
What wasn't a good decision, was keeping a certified nag like Gio in so long, moving from Albers so quick after a good inning and not trusting Roark at all.
Another bad decision was keeping Werth in with better defensive options or playing him continually, especially in Game 3 when Kendrick was 5/10 against Quintana and Werth had never faced him before. Or keeping Turner in leadoff despite Difo having a great year against lefties.
And Wieters, my god, he stayed in with the bases loaded when Lind could have pinch-hit for him early in the game and had Lobaton behind the dish.
This game was lost by weak players spearheaded by a weak manager too afraid to hurt feelings who also has a history of losing.
The Cubs are a good team, absolutely, but the Nats beat themselves this series without any help of umpires and it's freaking disgusting.
