Sometimes you need a scientist to help explain what other scientists are talking about. Luckily, sosh.com has @StupendousMan. Please take a look at this article if you are at all interested in what a batter sees in the batter's box:
A recent article, published in the journal PLOS ONE, describes experiments which show that as long as a batter can see the first half or so of a pitch’s trajectory, he can still put the bat in the correct place to make solid contact. The authors of this study, Contribution of Visual Information about Ball Trajectory to Baseball Hitting Accuracy, are a group of sports scientists in Japan. The lead author, Takatoshi Higuchi, works at Ritsumeikan University in Kyoto, while his co-authors are based in Waseda University, Nara Women’s University, and, in the case of former Japanese big-league pitcher Masakazu Watanabe, Fukuoka University. Their research was supported by the Japan Society for the Promotion of Science, which – disclaimer – has kindly funded some of my own collaborations with Japanese scientists.
