I'm much more worried for the Stros than most of the media thinks I should be, and was entering the series as well.
The Nats are the only team that can go toe to toe with the Astros on starting pitching, hugely important in the postseason. The Astros big advantage is their bats but their bats have been straight trash in the postseason. Like really, really trash.
Altuve is the only Stros hitter that is hitting over .265. Springer has been hitting dingers but he's batting .184. Alvarez, who has been nothing more than a liability this postseason, is actually out-hitting Springer, Correa, and Reddick for average with his whopping .205 avg. Gurriel feels like he's been Babe Ruth out there compared to the rest of the lineup and he's only hitting .229. The MVP has been invisible in the cleanup spot.
And all of that was against very modest starting pitching. Now they get probably 4 games of Scherzer/Strasburg of the potentially 6 remaining.
You can't win a World Series like that. I know the Nats' pen is trash, but for that to matter someone has to actually hit the damn ball. Forget Cole/Verlander/Greinke. The Astros bats have to come alive in a big way if they are going to win this thing and they've given absolutely zero indication of that happening at all this postseason.
