Baseball looks a lot like the game played 100 years ago. But it also looks very different in many crucial ways. Minorities can now play. The height of the mound has been changed. Night games are now played, with the help of lights. Technology—from the material of bats to the shape of gloves to the design of cleats—has evolved. Even the composition of baseballs is different. If all these things can change without eliciting much objection, then why would instant replay violate a tradition? And even if it did, it’s not clear that that tradition is a valuable one (as opposed to a neutral one or even a downright undesirable one).
