LThe Nationals have played The Cards 4 games this season and they won 3 of them.

I'm not sure who the Cardinals ace is but Wainwright is it or he's Ace B. The problem is he's been shaky recently and the Nats really pounded him out when they faced him.
Edwin Jackson was lights out when he faced the Cards this year.

He's coming off a great outing against Milwaukee. Jackson isn't the best pitcher for the Nats bit he pitches with a lot of heart. You can tell he's trying to pick up the slack for Strasburg but those are big shoes to fill.

Cardinals are a much better team when playing at home but these Nats are fierce. Top to bottom that team can pound the ball and I think they get the win tomorrow.
