The Red Sox are four games and 181 runs up on the Yankees, because baseball is really, really stupid sometimes. By third-order wins, the Sox are actually 18 up on the Yankees. Eighteen!
Unfortunately, we play in the real world. Oh God, why do we play in the real world?
For once, let's not only score a bunch more runs than the Yankees, but also win a bunch more games than them. Because coming up short in New York would likely take put the Sox somewhere they don't want to be with only two weeks to go.
