The team examined five major-league baseballs one each from the years 1963 1970 1989 1995 and 2000. They initially did simple bounce tests with the balls then dissected each for detailed examination. During the whole-ball bounce tests the two balls from 2000 and 1995 gave strikingly similar results; but those results were quite different from those of the other balls. Later tests with the bare “pill” ball core showed very similar patterns.
