For all the fuss this month about sign stealing, the key matchup in the World Series may have nothing to do with which team has the other team’s signs.
Sometimes, you don’t need the signs. Sometimes, the pitcher tells you what’s coming.
He may do it with his hands. He may do it with his glove. He may speed up on one pitch and slow down on another. But just as every poker player is looking for a “tell” from his opponent, every hitter should be alert for a “tell” from the opposing pitcher.
More often than you think, there’s one there.
