“ The team examined five major-league baseballs one each from the years 1963 1970 1989 1995 and 2000.

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.
