Out of curiousity, if Silver King were pitching today would you take him and his 709 IP over 1999's Pedro Martinez? I mean I guess King could pitch everyday even in today's modern game; just like he does in SimLeague. Or was he able to pitch so many innings because of a dead ball and because teams travelled by train and had more days off between games so he could rest a little longer. I'm not sure.
Before 1894 the distance from the mound to home was significantly shorter. Pitchers didn't have to throw as hard and because of this, they could pitch more often. Teams typically employed 2 man rotations back then. They did have more days off too, but not as many as you might figure since the leagues were much more compact geographically. The shift to a four man/ four day rotation occured in the five years after the pitching distance change,. As time went on, generally pitchers were given more rest and rotations went more strictly four-man. The shift to a five-man / five-day rotation didn't uccur until the 1970s. I think this was a result of lowering the mound in 1969, tho I have rarely read that. As the strike zones and ballparks shrunk in the 90s and 2000s, pitchers responded by throwing more hard breaking balls which are harsher on the arm. As a result a strict five man rotation replaced the five man/ five day rotation. Modern medical and sabermetric analysis as well as economic necessity has pushed back on the five man rotation a bit in the past few years but it remains the standard.
