Yea that makes more sense. Can't envision a scenario where the Nats sweep the Astros. They'd probably have to beat Cole twice, doesn't seem humanly possible.
The Yankees were by far the better matchup for the Nationals--more swing & miss in their lineup that the Nats SP could take advantage of. The talent disparity with the Astros is too wide and the Nats won't be able to minimize their bullpen the way they have previously.
