On this day in baseball history in...1918: Washington's Walter Johnson pitched a 1-0, 18-inning victory over Lefty Williams of the White Sox, who also went the distance.
The Time Walter Johnson Pitched 18 Innings in One Game!
Walter Johnson is one of the greatest pitchers of all time, and on May 15, 1918, he delivered a performance that stood out from any of his other games. He pitched a total of 18 innings in one game – and won! The game took place at Griffith Stadium against the defending World Series champion Chicago White Sox, and ended on a wild pitch by Lefty Williams, giving the Senators a 1-0 walk-off win.
For those 18 innings, Johnson gave up 10 hits, one walk, struck out 9, and gave up no runs. His earned run average dropped to just 0.98. Though he contributed just one hit in seven at bats, the hit actually put the Senators in the position to win the game in the 18th. From the Washington Herald’s game write up the next day:
“Walter Johnson and Eddie Ainsmith are credited with timely clouts [hits] which put the Nationals in the running. It happened in the eighteenth after Foster had popped out. Ainsmith singled to center and moved all the way to the far corner when Johnny Collins delayed a few seconds in recovering Johnson’s clout in the same territory.”

Needless to say, back then "pitch count" wasn't an issue. The chances are better today for someone to beat Joe Dimaggio's consecutive game hitting streak than someone duplicating that feat.
