Albert Einstein defined insanity as repeating the same mistakes and expecting different results. In baseball terminology this is called Ike Davis.
Good baseball teams in a slump have hope. If a team has talented players there is every reason to be optimistic. It's a 162-game season and, rest assure, tomorrow could be the day things turn around and a good team gets hot. Pitchers start pitching. Hitters start hitting. Closers close. The club wins six, seven, eight in a row, 15 of their next 20 games. Confidence is restored. See St. Louis Cardinals.
