Babe Adams of the Pittsburgh Pirates pitched an entire 21-inning game without issuing a single walk on July 17, 1914. It was the longest game pitched by a single pitcher in big league history in which that pitcher did not concede a base-on-balls. In the top of the 21st inning, Larry Doyle’s home run proved the deciding hit, giving the New York Giants the 3-1 victory. Rube Marquard of the Giants, who also went the distance in the game, allowed only two walks and gained the victory.

i wonder if he was thinking, “damn, i haven’t walked anyone yet” or was it just another 21 inning game for a pitcher in 1914.
I would be curious to know if he thought anything of it. I’d be surprised if he did. If it were me, by about the tenth inning, I would’ve been too weary to care, just grinding to the end.
