Criss-cross applesauce

By Tangotiger, 09:20 AM

Such very cool data.  I’ve always set the change in pitcher usage at around 1982/1983.  That’s when the starters were on a different usage pattern, and closers were on a different usage pattern.  That was my guess anyway.  If you look at the chart, the percentage of starts of 3 days and 5 days criss-crossed during 1979/1980.  And if you look at the 5+ days, the percentagejumps and plateaus from 1977 to 1987, and then another jump/plateau 1988 to 1997, and finally our current one from 1998 to present.

However, if you look at the % of starts of 3 or fewer days of rest minus % of starts 5 or greater days of rest, you get a wildly enormous transition from 1973 to 1981, after which, a plateau from 1982 to 1986, then another transition from 1987 to 1991, a plateau from 1992 to 1997, and a jump/plateau from 1998 to present.  This is what I remember, and I think it better describes the changing pattern of usage.

Studes, maybe you can add a new chart that shows just those three lines, the “3 and fewer”, “four”, and “5 and more”?
