The really surprising thing is that the Giants' swept the Tigers. The Giants held the Tigers scoreless in two games and to a .159/.243/.246 line in four world series games. That's a really good way to do business if you're a Giant, and a bad way to do business if you're a Tiger.
I loved the ending. Sergio Romo had thrown nothing but sliders to the two right-handed batters he faced in the Detroit 10th inning, until his final pitch. Then, he painted a fastball on the inside black to straighten up Miguel Cabrera for a called third strike. You can see on the video here (around the 0:28 mark) that Cabrera is has started his hands out, and is about to dive over the plate to go get a slider. Romo fooled him.
