Maybe next time Bumgarner will take the sure out at first base. Take a risk like that and it can come back to bite you.
FTFY.
Also, on these types of plays, it isn't all on the pitcher. Bumgarner was simply doing what his catcher (Buster Posey) told him to do. For all we know, it could've worked out; in this case, it didn't. And the design of AT&T Park didn't do the Giants any favours. There's no need to call anybody in these circumstances what you called Bumgarner in your original post.
Besides, it's not as if the Nationals are going to win the series anyway...I hope.
And if we're offering ALCS predictions, I'll offer 2:
a.) I think that whoever wins the ALCS is winning the World Series this year
b.)
Orioles in 7. Both teams are evenly matched & play in great atmospheres with genuine fan support. The Orioles' will have their atmosphere for a game 7.
