The last known time a team in the majors used a motorized vehicle — some clubs had actual cars — to relay relievers was 1995, when the Milwaukee Brewers shuttled them in a motorcycle with a sidecar.
Baseball historians have tracked the use of bullpen carts to 1950, when the Indians first used a "little red wagon." The first official use came in 1951 with the Chicago White Sox.
The Kansas City Athletics added one in 1955, and by the 1960s, the carts could be found across the majors and minors.
