The highest pitch count since 1990 is 172, by Tim Wakefield for the Pittsburgh Pirates against the Atlanta Braves on April 27, 1993; however, it should be known that Wakefield's primary pitch was the knuckleball, an off-speed pitch.

The biomechanics of pitching have been studied extensively.

[6] PITCHf/x uses algorithms to automatically classify every pitch by type, but these algorithms are imprecise.
