On September 7, 1974, pitching for the California Angels, Nolan Ryan, known for his velocity, became the first to have his pitch speed measured during a game. Rockwell International experts clocked the ball velocity at 100.8 miles per hour.
That was the fastest pitch ever recorded.
Yet last season over 50 pitchers in Major League Baseball threw 100 MPH and 140 more hit that velocity in the minor leagues. In September of 2010, Aroldis Chapman threw 105.1 MPH. Clearly, pitchers have gotten a lot faster, due to superior training and better scouting identifying athletes who will excel at pitching and getting them to play baseball rather than basketball or something else.
