While Major League Baseball roster is only 25 deep—26 in 2020 after a rule change—the reality is that close to double that play for a big league team over the course of the season due to call-ups, demotions, injuries, and trades. This is particularly true for a team like the 2019 Kansas City Royals, who were top heavy, very bad, and had limited depth in the minor leagues.
These nine players contributed to the 2019 Royals season and are in the record books as having done so. However, none played enough or were noteworthy enough to warrant their own individual discussion.
