On March 6, 2018 — 2018 – To celebrate their 20th anniversary this year, the Diamondbacks announce that they will re-introduce a contraption dating back to the days before the team existed: a bullpen cart. The modified golf carts were popular in the 1970s and early 1980s, but had seemingly gone the way of the dodo since that time.
