Cy Young holds what IMO is the most unbreakable record in baseball, and it’s not the most wins. It’s the most complete games: 749. In the present relief-pitcher era of baseball it’s rare to see a pitcher break into double figures for complete games in a season.
At the end of the day...Cy Young is still probably the greatest pitcher to ever pitch.
Is that true in the AL? I recall a world series with the White Sox against the Astros where it seems to me that each sox pitcher pitched a complete game, no relievers.
