It really is fitting that Stephen Strasburg is the one to win the World Series MVP for the Washington Nationals after being the first overall pick in 2009 that really started the movement for this title.
Honestly, Stephen Strasburg should be the MVP of the entire postseason with what he did.
For the entire postseason he had an ERA of 1.98 in 5 starts (1 relief appearance) with 47 strikeouts in 36.1 innings pitched.
In the World Series alone he gave up just 4 earned runs in 14.1 innings pitched on 12 hits and 3 walks with 14 strikeouts.
