Giants backup catcher Hector Sanchez made one start in the NLDS against the Reds and another in the NLCS versus the Cardinals. But the 22-year-old is unlikely to catch at all during the World Series.
Giants manager Bruce Bochy told Henry Schulman of the San Francisco Chronicle on Wednesday that Buster Posey will do "all the catching" throughout the Fall Classic. Sanchez could get a few looks at DH once the series shifts to Detroit, but he won't be behind the plate unless there's an emergency.
