Reader mail of the week: Regression based on playing time

By Tangotiger, 12:04 AM

About means regression: could playing time be used as a proxy for ability, to a degree? Say, if players who have around 620 PA hit .280, a player who has 620 PA would be regressed to .280; a player who has 140 PA might be regressed to .225.

Yes, absolutely and without question.  Back at the old Primer, there was actually a research piece along these lines.

PA is not something independent, and therefore, it should be used as a parameter to establish talent level.  This is obviously in something like hockey, where only the really good forwards play 20 minutes a game or the really good defensemen play 25 minutes a game.  It’s less obvious in baseball, but it’s still there.
