I have not been watching baseball closely enough. I just learned about the traditional ball flip to the first baseman from this article. “In every major-league game, each time the side is retired and the first baseman trots off the field, someone in the dugout tosses him a ball. It is the infield warm-up ball.” What other bits of baseball heritage have I been missing and what has been lost to the ages? On the opposite end, new baseball trends, the Oakland A’s pitching coach has been working with a sports medicine surgeon to map pitching motions and analyze the movements of good pitching. They hope to reduce injuries and keep the pitching staff in good form.
