ESPN.com – MLB – Schwarz: Calculated maneuvers
Two really interesting things in this survey. Evidence that average 9 inning pitch counts in the 1930s were 115. And Leo Mazzone saying he didn’t pay any attention to pitch counts.
And I’m reminded of a third interesting thing. Rany Jazayerli and Keith Woolner’s evidence that a high pitch count today means more ineffectiveness next time out. It isn’t a universal effect, but the correlation seems strong enough it’s worth considering when making pitching moves.
