Their pen was used heavily the last two days. Don't expect them to keep it up. Same to a lesser degree for the Nats.
They used everyone yesterday and everyone but 2 the game before, and everyone but 2 the game before that. They're good players who are exhausted. Case in point Jansen who is definitely cooked and I'd Imagine off-limits tonight, given his workload and struggles just in this series.
So was our pen. You can bet those guys will be will be available in a game like this.
