There were no less than 27 rookie eligible players used by the Diamondbacks this season, which blows away. Tunguska-style, the previous high for Arizona of 19 (most recently in 2016, also during the “Baby Backs” season of 2004). In fact, across the last century of baseball, that number has been surpassed just three times: the 1943 Athletics (then in Phillie) and the Marlins this season (not least due to their COVID woes) each used 28, and the 1998 Marlins set the all-time record with 29. For those of you on mobile, for whom the data below might not display so well, here’s the list.
