The Kansas City Royals made history in 2021 by becoming the first team ever to have five pitchers from the same draft class - Brady Singer, Kris Bubic, Daniel Lynch, Jackson Kowar, and Jonathan Heasley - start a game in the same season. All of them showed flashes throughout their young seasons, although some much more than others. Aside from these five starters, the Royals also had 45 games started this past season by other pitchers aged 28 and under. This doesn’t account for Mike Minor either, who started 28 games for the team in 2021.
The Royals have a surplus of quality starters with only flashes of greatness shown thus far.
