Here's the thing. They're not getting great pitching from mediocre pitching. Their elite defense is making their mediocre pitching look great. Their defense is the best in the majors, and it isn't even close.
Lorenzo Cain and Dyson were the best two defensive centerfielders in the AL this year. Move one to a corner, and add 3x Gold Glove winner Alex Gordon to the other outfield spot and nothing drops into that outfield. Salvador Perez caught 75 base stealers this season around a 35% clip and had a crucial one last night. Escobar and Moustakas are having very good years as well. The only weak link is Hosmer at first base, but he's looked fine to me.
And have you seen that bullpen? They have three qualified relievers who had ERA's in the 1.00s this year, and that's not including first round pick Finnegan.
They're sneaky good. Not the team I expected in the World Series, but the more I watch, the more I realize they deserve to be there.
