Relievers throw fastballs when facing other relievers - Baseball

The caveat to this piece of the Code is that for the most part, relievers don't step to the plate in close games, which gives their counterparts on the opposing team some leeway in their approach. "You'd probably give them all fastballs," said Dave LaRoche. "It was just a professional courtesy type of thing. Here it is — I'll give you a chance to hit it if you can."   -- Jason Turbow
