How long do starters go, how many relievers, etc.
Here’s the simplest measurement, one obtainable from Retrosheet game logs: the average number of pitchers used in one game by one team.
The DH is certainly a factor from 1973 on, but it looks like it was falling anyway in the two seasons prior.
I wonder if we’ve reached a limit at 4 per game. Might be the max for a 25-man roster.
More to come…
