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…
