Pitch Counts and the pitch count estimator for seasons past. Monday, May 11, 2015

Joba, Joba, Joba. The Yankees have finally moved Joba Chamberlain from the bullpen into the starting rotation. A big part of the decision depended on pitch count. Any time pitch count is mentioned it is for a particular game. However, the Yankees should consider Joba's pitch count for the season in deciding how to use him...
Tom Tango developed a pitch count estimator for seasons when pitches were not counted. See the above link. While there is no date, I think he did this in 2000. His example of Brad Radke and Randy Johnson concludes that Johnson threw about four pitches per batter faced and Radke threw about 3.5. Johnson threw 14% more pitches per batter faced. That's why the Yankees need to track Joba's cumulative pitch count, not merely track his innings.
How many pitches do starting pitchers throw in a season? How has that total varied over time?
Anybody actually know? In his new compromise talk Met GM Sandy Alderson is supposedly mentioning 180 innings as a regular season limit for Matt Harvey... then having Harvey also pitch in the tournament. Isn't that where this started? And are those 180 innings forgotten by Harvey's arm in the tournament?
