Or so says most major leaguers. The New York Times has a great story about that:
But despite its almost sacred place in the game, there is one little secret about batting practice: many players think it is a colossal waste of time, a mind-numbing, flaw-producing, strategically empty exercise. Eric Chavez of the Yankees is a veteran of 15 years of major league batting practice, but he thinks it has helped him about as much as staring at a wall for an hour.
“B.P. is part of baseball tradition,” Chavez said. “It’s fun for the fans; you try to hit a couple of balls in the stands. But in terms of work, what are you working on? It’s a 30-mile-per-hour pitch.”
But such is the nature of baseball. There is no sport that comes close to baseball in terms of “we do it this way because we’ve always done it this way” thinking. Why do batting practice? Because we’ve always done batting practice. Never mind that it’s kind of useless.
If some manager decided to scrap batting practice and did anything other than win the World Series, he’d be crucified. Doesn’t matter what the reason for the losing was, the “he got rid of batting practice!” argument would carry the day. Just ask any manager who tried to do closer by committee or anything else unorthodox about it. You play the non-conformist in baseball at your peril.
