Powerline had a post this week honoring Sandy Koufax and his performance in the 1965 World Series, in which they reported:
To an astonishing degree, that game was typical. Bill James did a statistical analysis of Sandy's career, tabulating his won-loss record when his team scored 5, 4, 3, 2, and 1 run. (The Dodgers hardly ever scored more than five.) James thus uncovered what he described as the most amazing statistic in the history of baseball: when the Dodgers scored just one run, Koufax's W-L record was better than .500.
I agree. That's simply unbelievable. I wonder if it has ever been true for any other pitcher who played as many games.
