Diamondbacks bringing back the bullpen cart in 2018

The Arizona Diamondbacks are bringing back the bullpen cart.
    
The Diamondbacks announced Tuesday that the team will use an OnTrac bullpen cart to transport relief pitchers from both bullpens at Chase Field prior to entering a game.
    
The last known use of a motorized vehicle in Major League Baseball was in 1995, when the Milwaukee Brewers used a motorcycle with a sidecar. Mike Fetters, Arizona's bullpen coach, was the closer for the Brewers that season.
    
Baseball historians have tracked the use of bullpen carts to 1950, when the Cleveland Indians first used a "little red wagon." The first official use came in 1951 with the Chicago White Sox. The Kansas City A's added one in 1955 and by the 1960s, the carts could be found across the majors and minors.
